    Opis:
    The article by Ptaszyński and Niedźwiedzki (2004) on vertebrate tracks from the well−known Tumlin Sandstone provides important documentation of the unique terrestrial ichnofauna of the Holy Cross Mountains in Poland. However, two of the major conclusions of this paper raise my objections. The authors propose a new position for the Permian–Triassic (P–Tr) boundary within the Buntsandstein succession of the regional lithostratigraphical scheme. In a conclusion of global significance, the authors find no signature of a mass extinction in the Late Permian land−dwelling tetrapod communities. Both of these issues are reviewed below.

    Opis:
    Jurassic tetrapod fossils are known from all of the continents, and their distribution documents a critical paleobiogeographic juncture in tetrapod evolution – the change from cosmopolitan Pangean tetrapod faunas to the provincialized faunas that characterize the late Mesozoic and Cenozoic. Two global tetrapod biochronological units (faunachrons) have been named for the Early Jurassic – Wassonian and Dawan – and reflect some Early Jurassic tetrapod cosmopolitanism. However, after the Dawan, a scattered and poorly-dated Middle Jurassic tetrapod record and a much better understood Upper Jurassic tetrapod record indicate that significant provincialization of the global tetrapod fauna had begun. Middle Jurassic tetrapod assemblages include distinct local genera of sauropod dinosaurs, which are large, mobile terrestrial tetrapods, and this suggests marked provinciality by Bajocian time. The obvious provincialism of well known Chinese Middle-Upper Jurassic dinosaur faunas also documents the end of tetrapod cosmopolitanism. The distribution of some Late Jurassic dinosaur taxa defines a province that extended from the western USA through Europe into eastern Africa. Provincial tetrapod biochronologies have already been proposed for this province and for the separate eastern Asian Late Jurassic province. Tetrapod footprints only identify two global assemblage zones, one of Early Jurassic and the other of Middle-Late Jurassic age. The incomplete state of Jurassic tetrapod biochronology reflects both an inadequate record with poor temporal constraints and a relative lack of study of the biostratigraphy of Jurassic fossil vertebrates.

    In accordance with the recommendations of the International Commission on Stratigraphy (ICS), the leading candidate for the Global Boundary Stratotype Section and Point (GSSP) of the base of the Bathonian Stage is located in the Ravin du B?s (Bas Auran area, SE France). This section was formally proposed as candidate nineteen years ago. A second potential candidate section is located in the Cabo Mondego area (Portugal). This Portuguese section, however, has not been formally proposed as a candidate for the Bathonian basal boundary stratotype. The formal selection and proposal of a GSSP for the Bathonian Stage is the responsibility of the Bathonian Working Group (BtWG) and is expected by September 2007. In accordance with the procedures to ratify GSSPs, a formal ballot on the selection and proposal of a GSSP for the Bathonian Stage, by post or email, by all members of the BtWG is the responsibility of the convenor and the International Subcommission on Jurassic Stratigraphy Executive, and will be carried out within this time scale.

    Opis:
    Middle Triassic (Muschelkalk) limestones and dolostones of southern Poland contain vertebrate remains, which can be used for palaeoecological and palaeogeographical analyses. The results presented concern vertebrate remains uncovered at four localities in Upper Silesia and one on Opole Silesia, a region representing the south-eastern margin of the Germanic Basin in Middle Triassic times. The most abundant remains in this assemblage are fish remains, comprising mostly actinopterygian teeth and scales. Chondrichthyan and sauropsid remains are less common. Reptilian finds include vertebrae, teeth and fragments of long bones, belonging to aquatic or semi-aquatic reptiles, such as nothosaurids, pachypleusorosaurids, and ichthyosaurids. Also, coprolites of possibly durophagous and predacious reptiles occur. In the stratigraphic column of Mikołów, actinopterygian remains are the most numerous and no distinct changes of the taxonomic composition occur. Although this assemblage differs from those described at other localities (Ząbkowice with numerous chondrichthyans, Żyglin, and Płaza with common sauropsid fossils), sampling bias has to be considered.

    Opis:
    This paper describes the vertebrate ichnofauna from the Tumlin Sandstone (Buntsandstein) of the Holy Cross Mountains in Poland. The footprint assemblage has previously been regarded as Early Triassic in age; however, ichnogenera characteristic of the Late Permian are now recognized. Lack of representatives of the ichnofamily Chirotheriidae, characteristic of continental Triassic sediments worldwide, also indicates a Permian rather than a Triassic age for the studied assemblage. Three ichnogenera (Batrachichnus, Limnopus, and Amphisauropus) produced by amphibians are recognized, the remainder (Varanopus, Chelichnus, Dimetropus, Rhynchosauroides, Palmichnus, Paradoxichnium, and Phalangichnus) being of reptilian origin. Batrachichnus cf. salamandroides (Geinitz, 1861), Limnopus cf. zeilleri (Delage, 1912), Amphisauropus cf. latus Haubold, 1970, Varanopus aff. microdactylus (Pabst, 1896), Chelichnus cf. duncani (Owen, 1842), and Dimetropussp. are recorded in the Lower Buntsandstein for the first time. The following new ichnospecies are erected: Rhynchosauroides kuletae ichnosp. nov., Palmichnus lacertoides ichnosp. nov., Paradoxichnium tumlinense ichnosp. nov., Phalangichnus gradzinskii ichnosp. nov., and Phalangichnus gagoli ichnosp. nov.

    Gastroliths (stomach stones) are known from many extant and extinct vertebrates, including dinosaurs. Reported here is the first unambiguous record of gastroliths in an ornithopod dinosaur. Clusters of small stones found in the abdominal region of three articulated skeletons of Gasparinisaura cincosaltensis were identified as gastroliths on the basis of taphonomic and sedimentologic evidence. The large number of stones found in each individual, their size, and the fact that Gasparinisaura cincosaltensis was herbivorous, all suggest that they were ingested as a result of lithophagy rather than accidental swallowing.

    Opis:
    We report a Late Cretaceous chemosynthetic community fueled by decomposing basal leatherback sea turtle on the ocean floor in the western Pacific. The fossil association representing this community has been recovered from the matrix of a concretion containing a single carapace of Mesodermochelys sp. from Late Cretaceous outer shelf to upper slope deposit of northern Hokkaido, Japan. The carapace displays boreholes most likely performed by boring bivalves, and is associated with molluscan shells, mainly Provanna cf. nakagawensis and Thyasira tanabei. Since this association is similar to fauna already known from Late Cretaceous hydrocarbon seeps, sunken wood, and plesiosaur-falls in Hokkaido, it is suggested that all types of chemosynthesis-based communities in the Late Cretaceous of western Pacific may have belonged to the same regional pool of animals and were not yet fully differentiated into three independent types of communities as it is known today. This finding also indicates that the sulfophilic stage of the vertebrate-fall communities was supported not only by plesiosaur carcasses, which were previously reported, but also by sea turtle carcasses. It highlights the possibility of surviving vertebrate-fall communities through the end-Cretaceous mass extinction event on carcasses of sea turtles which are the only large marine vertebrates surviving this event.

    Opis:
    The Ha Nohana palaeosurface in southern Lesotho preserves tridactyl and tetradactyl tracks and trackways attributable to Early Jurassic bipedal, theropod-like dinosaurs. Complementary sedimentological and ichnological observations along the palaeosurface and in the strata below and above it allow detailed interpretations of climatically driven changes in this southern Gondwana palaeoecosystem. Sedimentological evidence suggests trackmaking under a semi-arid climate with heavy storms and episodic flash flooding that induced ephemeral, unconfined sheetwashes. The palaeosurface is overlain by rhythmically bedded, organic-matter rich mudstones that formed in a deep, stratified lake indicative of a longer and wetter period in the history of the site. The unique morphological details of the Ha Nohana tracks help refine the properties of the substrate during track making, the ichnotaxonomic affinities of the footprints and the interpretation of the foot movement relative to the substrate. Two footprint morphotypes, ~ 300 m apart, are defined on the palaeosurface. Tracks of morphotype I are tridactyl, shallow, contain digital pad impressions and were impressed on a firm, sand rippled substrate that underwent desiccation. Conversely, tracks of morphotype II are tetradactyl, deep, and have an elongated posterior region. These tracks are preserved on the surface of a massive sandstone and are associated with soft sediment collapse structures related to the animal’s foot sinking into the water-saturated, malleable sediment layer. Morphotype II tracks show that as the animal waded across the substrate, the liquefied sediment lost its cohesive strength and could only partially support the weight of the animal. In so doing, the animal’s foot sunk deep enough into the sediment such that the impression of the metatarsal and digit I (hallux) are now visible. Thus, the palaeosurface was walked on by small-to-medium sized theropods that traversed over ripple marks in firmer moist sand, as well as a larger theropod that tottered through water-logged sand.

    Opis:
    This study describes the palaeoichnology of the Malhao Dune Field (Pleistocene), the first report of vertebrate tracksites from all the Cenozoic from Portugal. At least 14 stratigraphic horizons with mammal and bird foot prints and trackways occur, including those of elephants. Concave epirelief footprints produced by elephants show four feet with four toes imprints on each foot and heteropody in a narrow gauge. The presence of three possibly parallel trackways points to gregarious behavior of sub-adults/fe males of Elephas antiquus. The ichnospecies Proboscipeda panfamilia, found in the Malhao and Pessegueiro sectors, represents possibly the first Pleistocene elephant trackways, and record one of the latest occurrences of E. antiquus in Europe. The new ichnogenus and ichnospecies Leporidichnites malhaoi igen. et isp. nov., interpreted as lagomorph tracks, are also described.

    Opis:
    Recently, new material of the peculiar tetrapod Sclerothorax hypselonotusfrom the Middle Buntsandstein (Olenekian) of north−central Germany has emerged that reveals the anatomy of the skull and anterior postcranial skeleton in detail. Despite differences in preservation, all previous plus the new finds of Sclerothorax are identified as belonging to the same taxon. Sclerothorax is characterized by various autapomorphies (subquadrangular skull being widest in snout region, extreme height of thoracal neural spines in mid−trunk region, rhomboidal interclavicle longer than skull). Despite its peculiar skull roof, the palate and mandible are consistent with those of capitosauroid stereospondyls in the presence of large muscular pockets on the basal plate, a flattened edentulous parasphenoid, a long basicranial suture, a large hamate process in the mandible, and a falciform crest in the occipital part of the cheek. In order to elucidate the phylogenetic position of Sclerothorax, we performed a cladistic analysis of 18 taxa and 70 characters from all parts of the skeleton. According to our results, Sclerothorax is nested well within the higher stereospondyls, forming the sister taxon of capitosauroids. Palaeobiologically, Sclerothorax is interesting for its several characters believed to correlate with a terrestrial life, although this is contrasted by the possession of well−established lateral line sulci.

    Opis:
    A new ichnosite in southwest Lesotho (Upper Moyeni; Quthing District) is located within the uppermost part of the highly fossiliferous Elliot Formation, ~35 m below the conformably overlying Clarens Formation and ~65 m above the world-renowned Lower Moyeni ichnosite. While the Lower Moyeni site preserves diverse Early Jurassic ichnofossils, the ichnites at the Upper Moyeni comprise one vertebrate burrow and ~50 tridactyl tracks with footprint lengths between 15 and 51 cm. Many of the tracks preserve digital pad impressions, claw marks and displacement rims, all related to substrate conditions. The morphometric parameters of the Upper Moyeni tracks are consistent with Grallator, Eubrontes and Kayentapus. Several larger tracks with footprint lengths > 40 cm are Kayentapus-like and Eubrontes-like, and are comparable to previously described very large theropods tracks with lengths > 50 cm from the uppermost Elliot and Clarens formations. On the basis of sedimentological and ichnological evidence, the Upper Moyeni ichnofossils were formed in a palaeolandscape with small rivers and shallow lakes by burrowing tetrapods and a variety of bipedal dinosaurs (theropods), some of which were up to 7–8 m in body length. The Upper Moyeni tracks, together with the other very large tracks from coeval locations in southern Africa, collectively highlight the tendency towards increasing diversity in size of tridactyl tracks and by extension theropod trackmaker body size body size, which runs in tandem with the increasing diversity of non-sauropod, sauropodomorph body fossils in the Sinemurian-Pliensbachian of southern Gondwana.

    Opis:
    The article focuses on changes in terrestrial vertebrate fauna of Niebieskie Źródła (Blue Springs) Nature Reserve that occurred between two censuses carried out in the area. The first census was carried out in the period of 1968-1970, and the second census in the period of 1998-1999. In 1998-1999 the occurrence of four species of amphibians, 41 of birds and 15 of mammals was recorded. In comparison with investigations from 1968-1970 two species of amphibians, two species of mammals, and nine species of birds were found to have disappeared from the reserve. In the census carried out in 1998 and 1999 we recorded 22 new species of vertebrates: one new species of amphibian, five species of mammals, and 16 species of birds. The recent observations showed a decline in the abundance of amphibian species in the reserve, especially in the closest vicinity to the urban development around the city of Tomaszów Mazowiecki. The quantitative data on birds showed an increase in the numbers and abundance, which was mainly pronounced in the group of forest species, especially cavity and shrub nesters. We suggest that these changes are directly related to the succession of forest vegetation and its developing vertical structure, as well as to an increase in the forestation of the reserve area.

    Opis:
    Computer modelling related to the real dimensions of both the whole filament and the myosin molecule subfragments has revealed two alternative modes for myosin molecule packing which lead to the head disposition similar to that observed by EM on the surface of the cross-bridge zone of the relaxed vertebrate skeletal muscle thick filaments. One of the modes has been known for three decades and is usually incorporated into the so-called three-stranded model. The new mode differs from the former one in two aspects: (1) myosin heads are grouped into asymmetrical cross-bridge crowns instead of symmetrical ones; (2) not the whole myosin tail, but only a 43-nm C-terminus of each of them is straightened and near-parallel to the filament axis, the rest of the tail is twisted. Concurrent exploration of these alternative modes has revealed their influence on the filament features. The parameter values for the filament models as well as for the building units depicting the myosin molecule subfragments are verified by experimental data found in the literature. On the basis of the new mode for myosin molecule packing a complete bipolar structure of the thick filament is created.

    Opis:
    Fossil avian and reptilian eggs and eggshells, from the Cretaceous of Mongolia and USSR (Kazakhstan, Zaisan basin) as well as samples of dinosaurian and the Eocene avian eggshells from USA, China, France and Argentina were studied. Methodological, terminological and biomineralization aspects of eggshell structure are discussed. Considered are different classifications of eggshell according to the structural levels of eggshell matter organization (texture, general histostructure, superficial morphology). Basic types, morphotypes, types of pore system and types of surface ornamentation are the main structural categories employed in the systematic description of fossil material. About 18 groups of fossil eggshells referred to turtles, geckoes, crocodiles, and to 14 “families” or dinosaur and bird oological remains are described. Their composition, occurence, paleobiology and systematics are shortly presented.
    Praca zawiera przegląd budowy skorup jaj gadzich i ptasich oraz propozycją ujednoliconej terminologii oologicznej (fig. 1—8, tab. 1—2). Zbadany materiał obejmuje szczątki kredowych i kenozoicznych jaj gadzich i ptasich z Mongolii, Chin, Azji Środkowej, Francji, USA i Argentyny (pl. 21—39). Autor podaje kryteria klasyfikacji jaj na podstawie skorupy. Wyróżnia kilka poziomów organizacji strukturalnej skorup jaj: teksturę (ultrastrukturalne postaci biomineralizacji), histostrukturę ogólną i ogólną morfologię. Omawia i nazywa typy systemu porów oddechowych i ornamentacji zewnętrznej powierzchni skorupy. Na tej podstawie wyróżnia zasadnicze typy i morfotypy, oparte przede wszystkim na kryteriach ultra- i mikrostrukturalnych, jako najbardziej stabilnych i użytecznych diagnostycznie u grup współczesnych. Parataksonomiczny podział jaj kopalnych obejmuje 14 „rodzin” jaj dinozaurów i 18 grup jaj przypisanych krokodylom, żółwiom i gekkonom. Formalne opisy zawierają obok omówienia swoistych cech budowy skorup zaliczonych do poszczególnych grup także dane o ich występowaniu, spostrzeżenia paleobiologiczne i próbę powiązania parataksonów z grupami naturalnymi organizmów rodzicielskich.

    Opis:
    Age assignments of Triassic tetrapod fossils can be achieved by direct reference to a scheme of Triassic land-vertebrate faunachrons (LVFs) that correlates Triassic tetrapod fossil assemblages to each other based solely on the tetrapod fossils. Correlation of Triassic tetrapod assemblages to the standard global chronostratigraphic scale (SGCS, the “marine timescale”) is a separate cross correlation between the vertebrate biochronology and marine biochronology that usually relies on other data (e. g., palynostratigraphy, magnetostratigraphy, radioisotopic ages) to be completed. Late Triassic tetrapod fossils in southern Poland are found at two stratigraphic positions, the Krasiejów and Lisowice levels. The tetrapod assemblage of the Krasiejów level is assigned to the early Adamanian LVF based primarily on the stratigraphic overlap of the phytosaur Parasuchus with the Adamanian index aetosaur Stagonolepis. The amphibians Cyclotosaurus and Gerrothorax, a Proterochersis-like turtle and the aetosaur Paratypothorax from the Lisowice level indicate it is assignable to the Revueltian LVF. Cross correlations to the SGCS are less definitive, but suggest that the Krasiejów level is late Carnian and the Lisowice level is early/middle Norian. However, this correlation of the Krasiejów level is confounded by disagreements over correlation of the marine Carnian–Norian boundary to nonmarine strata. Indeed, the possibility that the Krasiejów tetrapods fill a gap in the early Norian record of tetrapods merits consideration. Such difficulties emphasize the value of correlating tetrapod assemblages to each other using a land-vertebrate biostratigraphy/biochronology, instead of immediately attempting the more problematic correlation to the SGCS.

    Opis:
    During the Late Triassic, metoposaurids were one of the last significant families of temnospondyl amphibians, and they have long been used in the correlation of Late Triassic tetrapod assemblages. Their fossil record extends across much of Late Triassic Pangea, including important metoposaurid fossils from the USA, Canada, Portugal, Germany, Poland, Morocco, India and Madagascar. Six genera of metoposarids are recognized: 1) Adamanian-Apachean Apachesaurus, endemic to the western USA, 2) Otischalkian Arganasaurus and Dutuitosaurus, endemic to Morocco, 3) Otischalkian-Revueltian Koskinonodon, endemic to the western USA, 4) Panthasaurus from the Otischalkian of India, and 5) Otischalkian-Adamanian Metoposaurus, known from the western USA, eastern Canada, Portugal, Italy, Germany, and Poland. Of the metoposaurid genera, only Metoposaurus has a broad enough palaeogeographic distribution and relatively restricted temporal range to be of biochronological value; its biochron identifies the Otischalkian–Adamanian (middle–late Carnian). The oldest metoposaurids are of middle Carnian age, the age of the Carnian pluvial episode of global climate. The middle Carnian broad palaeogeographic distribution, diversity and cosmopolitanism of the metoposaurids, followed by reduced diversity and relative endemism, likely indicates that climate changes were an important factor in their evolution.

    Opis:
    Conodonts, a large group of tiny extinct marine animals ranging in age from the Late Cambrian to Late Triassic (ca. 500 to 200 Mya), are usually considered as jawless vertebrates. Their only commonly occurring fossilized remains are minute, phosphatic, teeth−like elements of their feeding apparatuses. In most of the early conodonts the elements were conical and strongly elongated. Many of them are characterized by possession of a deep, longitudinal groove, usually associated with sharp edges or ridges. A comparative study of the grooved elements and venomous teeth and spines of living and extinct vertebrates strongly suggests that the groove in conodonts was also used for delivery of venom. Structural convergence of the conodont apparatus Panderodus with the grasping apparatus of chaetognaths, a group of extant, venomous invertebrate predators of similarly ancient origin, provides additional support for this conclusion.

In order to account for this distribution, two ways of dispersal bypassing Africa have been proposed.

    Opis:
    The palaeoecology of three Late Cretaceous snakes is evaluated. Pachyophis woodwardi Nopcsa, 1923 and Pachyrhachis problematicus Haas, 1979, are Cenomanian in age and are found in carbonate rocks deposited in marine inter-reef basin environments of the European and African Tethys Sea. Dinilysia patagonica Woodward, 1901, Coniacian in age, is considered closely allied to Living anilioid snakes, and is found in clastic rocks deposited in a terrestrial inter-dune basin environment in northern Patagonia, Argentina. All three snakes are known from well preserved and articulated specimens found in sediments where detailed sedimentological and taphonomic analyses are possible. Pachyophis and Pachyrhachis were laterally compressed, have pachyostotic ribs and vertebrae, and small, narrow heads. These two snakes are interpreted as aquatic predators living in and around the margins of reef mounds on a shallow water carbonate platform. Dinilysia was a large bodied snake with a relatively large head, and is interpreted here as a terrestrial predator that lived in a dry, interdune basin environment dominated by aeolian sedimentation. Sedimentary units preserve ichnological evidence of burrowing insects and rooting plants.

    Opis:
    A diverse microvertebrate fauna is described from the Virgin Hills and Napier formations, Bugle Gap Limestone Canning Basin, Western Australia. Measured sections at Horse Spring and Casey Falls (Virgin Hills Formation) and South Oscar Range (Napier Formation) comprise proximal to distal slope carbonates ranging in age from the Late Devonian Frasnian to middle Famennian. A total of 18 chondrichthyan taxa are identified based on teeth, including the first record of Thrinacodus tranquillus, Cladoides wildungensis, Protacrodus serra and Lissodus lusavorichi from the Canning Basin. A new species, Diademodus dominicus sp. nov. is also described and provides the first record of this genus outside of Laurussia. In addition, the upper range of Australolepis seddoni has been extended to Late Devonian conodont Zone 11, making it the youngest known occurrence for this species. The Virgin Hills and Napier formations microvertebrate faunas show close affinities to faunas recovered from other areas of Gondwana, including eastern Australia, Iran, Morocco and South China, which is consistent with known conodont and trilobite faunas of the same age.

    Opis:
    Three genera of xenacanths, based on isolated teeth, occur in the lepospondyl (amphibian)−dominated fauna from the upper Black Prince Limestone (late Bashkirian). Orthacanthus donnelljohnsi sp. nov. teeth, with carinae lacking serrations on the compressed principal cusps, and only one intermediate cusp, represent both adult and juvenile teeth. Heterodonty occurs in both adult and juvenile dentitions. The absence of serrations is unique among Pennsylvanian species of Orthacanthus. Teeth with often highly asymmetrical bases with an aborally−flexed lingual marginal flange (= anterolingual shelf) and a single intermediate cusp are assigned to Triodus elpia sp. nov. A central foramen occurs in the base, unlike most other species; the moderately compressed principal cusps bear generally straight cristae. They represent the first reported occurrence of Triodus in the Paleozoic of North America. Five teeth, with cristae extending from the cusps onto their bases, belong to Bransonella. Two are questionably assigned to Bransonella nebraskensis, one to B. ?lingulata with its labio−lingually elongated apical button and smaller than normal intermediate cusp, and one each to Bransonella sp. “A” and “B”. Bransonella sp. “A” has a base wider (labio−lingual) than long, the reverse of the other Bransonella teeth. Bransonella sp. “B” is distinctly different, as it lacks an intermediate cusp (as in some B. lingulata teeth), and the basal tubercle is beneath one of the cusps (with no evidence of deformity).

    Opis:
    Extant porpoises (Phocoenidae) are odontocetes characterized by their small size, short and wide rostrum, late (or absent) completion of epiphyseal ankylosis in the vertebral column (= physical maturity), and short life cycles, all of which are thought to have resulted from progenetic evolution. We describe a small fossil phocoenid from the lower Pliocene Koetoi Formation of Hokkaido (northern Japan), preserving a small, narrow rostrum, as well as anteroposteriorly elongate thoracic and lumbar vertebral centra with completely fused epiphyses. Physical maturity in this specimen occurred significantly earlier than in extant phocoenids, as shown by dental data indicating that the specimen died at only four years of age. The difference between the present material and extant porpoises may be attributable to different growth rates during ontogeny. The long centra and caudally inclined neural spines of the specimen from Hokkaido are primitive characters among phocoenids. By contrast, the great height of its neural spines is highly derived, even among extant species, and suggestive of a fast swimmer. In terms of its vertebral morphology, the new specimen falls within a morphological continuum defined by the archaic Numataphocoena yamashitai and the highly derived vertebral morphology of Phocoenoides dalli. Phocoenid vertebral evolution has been complex and frequently convergent, as opposed to stepwise and unidirectional. The different vertebral morphologies of the new specimen and the contemporaneous extinct taxa Numataphocoena and Piscolithax longirostris indicate that they were adapted to different environments.

    Opis:
    Didelphimorph marsupials were widely distributed in Asia during the Cenozoic, but their occurrence in the Indian subcontinent has not so far been demonstrated. Here, we describe a new herpetotheriid marsupial Asiadidelphis akbarbugtiisp. nov. from the early Oligocene Bugti Member of the Chitarwata Formation, Bugti Hills, Pakistan. The discovery of the herpetotheriids in the Oligocene of Pakistan represents the most southern occurrence of the family, which was thought to have occurred only to the north of the Alpine−Himalayan Suture. Our data suggest that episodic faunal exchanges occurred between the Asian mainland and the Indian subcontinent during the late Paleogene, and that the southern Asian faunas were not as completely isolated by the Himalayan chain as formerly believed.

    Opis:
    The objective of this report is to document first Mesozoic occurrences of chemosynthesis−based communities developed on large marine reptile carcasses. Micro−grazing provannid gastropods (typical of chemosynthetic communities) are associated with plesiosaurid skeletons in the Upper Cretaceous deposits of Hokkaido, northern Japan. The cancellous bones of the examined plesiosaurid bones contain a ubiquity of iron sulfides within the bone trabeculae, which provides evidence of anaerobic sulfate reduction of the bone lipids. We also report numerous microborings in the bone trabeculae, which might result from the activity of sulfur−oxidizing bacteria. This finding addresses the hotly debated problem of the emergence and radiation of whale bone faunas. We postulate that vertebrate bone environments in the Northwest Pacific region were settled repeatedly by animals from a regional pool of chemosynthesis−based communities that flourished in the methane seeps and/or hot vents that were present during the Late Cretaceous–Miocene.

    Opis:
    The Sołtyków exposure is an old, long time abandoned clay pit. This exposure became known as a classical outcrop of alluvial-lacustrine deposits. Floral remains point to the earliest Jurassic (Lias 1-2) age, and the sequence stratigraphic correlation allows to narrow its age range to the Early Hettangian (Planorbis biochronozone). Sołtyków exposure fits the avulsion-controlled (crevassing- anastomosing) fluvial sedimentation model, however, some features such as laterally-accreted bedding point also to presence of high-sinuosity/meandering streams. Relatively thick and individualised package of lacustrine deposits occurring in the Sołtyków outcrop points to some permanency of the lake/swamp area during deposition of the sediments visible in the outcrop. Palaeosols are both of Podzol and Histosol type. The plant fossils in the Sołtyków exposure are very abundant and well preserved. The list of plants includes Neocalamites, the matoniacean, osmundacean and other indeterminate ferns, as well as pteridosperms, benettitaleans and conifers. Non-marine trace fossils comprise Coprinisphaera, Scoyeniaand aquatic Mermia ichnofacies. Other fossils that occur in Sołtyko?w are represented by Unionidae freshwater bivalve assemblage, insect remains, fresh-water ostracodes and scales of palaeoniscid fish. The Sołtyków exposure is well known Early Jurassic tracksite with numerous dinosaur footprints, mainly left by theropods and sauropods, and early mammalian footprints. The dinosaur nesting ground was also described. Recently, the Sołtyków exposure has been declared a natural reserve. Nature conservation problems are discussed. Due to many unique finds in Sołtyków (the oldest known evidence of gregarious ethology of dinosaurs, the biggest known Early Jurassic theropod footprints, rich and well-preserved invertebrate ichnoforms and plant remains, this exposure should be enlisted on the UNESCO World Heritage List (in geological cathegory). Moreover, the idea of “Kamienna Valley” geopark, comprising Sołtyków and other valuable outcrops in the region, is introduced.

    Numerous specimens of vertebrate tracks were discovered in the uppermost Röt (uppermost Buntsandstein) deposits of "Krynki Beds" that crop out at Witulin, Parszów, Małe Jodło, Jarugi, Bliżyn, and Sorbin in the north-eastern and central margin of the Holy Cross Mountains, Poland. The following vertebrate ichnotaxa were identified in these localities: Chirotherium barthii Kaup, 1835; Chirotherium cf. sickleri; Synaptichnium cf. diabloense; Isochirotherium herculis (Egerton, 1839); ? Isochirotherium cf. herculis; Isochirotherium isp.; Chirotheriidae indet.; Rhynchosauroides isp., and Rhynchosauroidae indet. The ichnoassemblage from the "Krynki Beds" is very similar to ichnoassociations which are known from: 1) latest Early and early Middle Triassic (Upper Buntsandstein) deposits of the Central European Basin, 2) latest Early and early Middle Triassic Moenkopi Formation of USA, 3) Middle Triassic deposits of United Kingdom, France and Italy.

    Opis:
    Lithostratigraphic division of the Upper Silesian Keuper continental succession belongs to abandoned matters, even if newly-discovered sites with unique vertebrate faunas highlight an increasing request to more precise designation of their stratigraphic setting. As a result of multidisciplinary grant and with a guide use of new borehole sections, a major lithostratigraphic unit is formally proposed for the middle Keuper (i.e., above the Schilfsandstein; Stuttgart Formation in Stratigraphische Tabelle von Deutschland, 2002), based on previously inaccurately used unit, Grabowa Formation of Bilan (1976). The re-defined Formation of Variegated Mudstones and Carbonates from Grabowa includes Upper Gypsum Beds and Steinmergelkeuper in traditional scheme from Germany (=Weser and Arnstadt Formations), and generally correlates with the Norian stage. Two bone-bearing horizons (Krasiejów and Lisowice) are placed within the unit, which is completely subdivided in three members: Ozimek (mudstone-evaporate), Patoka (marly mudstone-sandstone) and WoŸniki (limestone).

    Opis:
    A detailed sedimentological study of the Lower-Middle Muschelkalk (Middle Triassic) carbonate succession exposed at the “Stare Gliny” quarry near Olkusz (Kraków-Silesia region, southern Poland) revealed numerous vertebrate remains within its lowermost sedimentary unit. This 7-m-thick package onlaps a gently-inclined surface of a paleoisland made of the Devonian (Givetian) dolostones, and was deposited during a transgressive phase of the second Middle Triassic transgression onto the southern Poland. The package consists largely of: 1) unfossiliferous dolosiltites and fine-grained dolarenites, the tops of which commonly contain root molds and small-scale karstic forms; 2) breccias (minor conglomerates) with lithoclasts of Givetian dolostones; 3) dolocretes; and 4) dolomitic shales. This lithofacies association represents a restricted lagoon which experienced longer periods of emersion. A minor occurrence of cryptalgal laminites reflects only temporary sedimentation in the intertidal zone of a tidal flat. The bone fragments occur within all types of lithofacies, but the macroscopically distinguishable specimens have been found exclusively in the dolocretes. The poor preservation and advanced disarticulation of bones hinder unequivocal assessment of their affinity. The small size of bones suggests that they represent prolacertiforms (perhaps juvenile Macrocnemus) or other small archosauromorphs similar in sizes to Protorosaurus or Czatkowiella whose remains were found in the 1950s within cave deposits, in the same outcrop. Macrocnemus widely inhabited Middle Triassic lagoons and tidal flats across Paleo-Europe and thus seems to fit well to the peritidal setting surrounding the “Stare Gliny” paleoisland. The bone-bearing package occurs 30 metres below the 5-m-thick oncolitic package that is widely regarded as a correlation horizon over the entire Kraków-Silesia region, and 15 metres below the sequence boundary marking the top of the Górażdże Beds in the Opole region and the Olkusz Bedsin the Kraków-Silesiaregion.On the basis of the secor relations,a conclusion can be made that the vertebrate assemblage is Bithynian/Pelsonian (middle Anisian) in age.

    Opis:
    The major goal of the project “The evolution of terrestrial environments of the Upper Silesian Keuper as biotopes of vertebrates”, granted for Grzegorz Racki by the Ministry of Science and Higher Education (2009-2013), was an exhaustive, integrated study of the bone-enriched middle Keuper interval in terms of stratigraphy, sedimentology, mineralogy and geochemistry. The new website “Bone-bearing Keuper of the Upper Silesia, southern Poland” (http://www.ing.pan.pl/Keuper/Bone-bearing_Keuper-1.htm)presents in English the results of this project. The significant achievements are only a starting point to a comprehensive presentation of the complex Keuper themes, jointly with an extensive repository of regional literature (above 420 full-texted publications since 1790). In addition, the main results of the grant, as well as diversity of their implications for future studies are summarized herein, with emphasis on controversial geochronological aspects in vertebrate paleontology (how many bone-rich levels?), and in a broad historical context.

    Vertebrate footprints are abundant in the Buntsandstein of the Holy Cross Mountains (central Poland) and have been documented in numer-ous publications. A new site vertebrate trackside has been discovered in near Suchedniów. Chirotheriidae (Synaptichnium sp., Chirotherium barthii, and Brachychirotherium sp.), Rhynchosauroidae (Rhynchosauroides sp.), and probably amphibian footprints (cf. Capitosauroides sp.) are reported from the lower part of the Upper Buntsandstein Baranów Formation (complex of different fluvial deposits) exposed at Kopulak quarry. Differentiated invertebrate ichnofossils (Cruziana problematica, Scoyenia sp., Palaeophycus sp., Skolithos sp., Lockeia sp., and cf. Gordia sp.) and plant remains have been also found in this site. Three types of vertebrate subaqueous traces (footprints of swimming animals) are identified: (1) swim traces - structures preserved as digits or claws scratches; (2) partially preserved pes or manus imprints; (3) other enigmatic traces -referred to as “problematic forms”.

    Opis:
    The paper presents new data on origin of parallel orientation of modern assemblages of bone remains in dry, terrestrial environment, unaffected by any influence of hydraulic processes. The studies were carried out in the gallery no. 6 of ancient underground millstone quarry situated in forests near the Potok Senderki village, Central Roztocze Upland. The studied material included animal bone remains found in dry gallery, presently inhabited by red foxes (Vulpes vulpes L.). Azimuths of long bone axes as well as strike azimuths o vertical adit walls which confine occurrence of bone clusters, were measured using geological compass. The obtained results make it possible to conclude that linear parallel orientation of bone remains may occur in a dry, terrestrial environment. Such orientation of clusters is formed mainly due to repetitive movement of carnivores along vertical walls of the adit whereas no influence of hydraulic processes is needed here. The presence of a distinct, preferred orientation of the bones requires interaction of two specific factors: the place has to be inhabited by carnivorous animals for a long time (at least for a few months) and the corridor, along which animals move, has to be bounded by steep to vertical walls. Caves are particularly predisposed type of sites, where the occurrence of linear bone orientation may be expected. The studies were dealing with effects of actualistic processes but the described situation and the obtained conclusions may be valid in the case of fossil bone assemblages, for example those of the Pleistocene age.

Thelodont scales referred here to Australolepis sp. cf. A. seddoni come from near Śniadka village, from samples dated as hemiansatus to rhenanus/varcus zones. This increases the known range for the genus from its original find in Western Australia.

    Opis:
    Obserwujemy obecnie szóste, plejstoceńsko-holoceńskie wielkie wymieranie. Jednym z istotnych czynników przyczyniających się do dramatycznego spadku różnorodności dzikiej fauny i flory są zmiany klimatu. Ludzkość podjęła walkę ze zmianami klimatu w 1992 roku, kiedy to w trakcie Szczytu Ziemi w Rio de Janeiro przyjęto Ramową Konwencję Narodów Zjednoczonych w sprawie Zmian Klimatu. Niestety efektów tych wysiłków nie widać. Wzrost emisji gazów cieplarnianych doprowadzi do wymarcia połowy gatunków na Ziemi do końca wieku. Ograniczenie wzrostu temperatury do 2°C (w stosunku do ery przedindustrialnej) do 2100 roku oznaczać będzie zmniejszenie różnorodności gatunkowej o 25%. Naukowcy przestrzegają, że jeśli nie podejmiemy natychmiastowych działań, czeka nas katastrofalna utrata różnorodności biologicznej. Dzikie zwierzęta kręgowe już dzisiaj stanowią zaledwie 4% biomasy wszystkich kręgowców, dramatycznie niewiele w porównaniu z biomasą zwierząt hodowlanych.
    В настоящее время мы наблюдаем шестое плейстоцен-голоценовое великое вымирание. Изменение климата является одним из важных факторов, способствующих резкому сокращению разнообразия дикой природы. Человечество взялось за борьбу с изменением климата в 1992 году, приняв Рамочную конвенцию ООН об изменении климата на Саммите Земли в Рио-де-Жанейро. К сожалению, результаты этих усилий не видны. Увеличение выбросов парниковых газов приведет к исчезновению половины видов на Земле к концу века. Ограничение повышения температуры до 2°C (по сравнению с доиндустриальной эпохой) до 2100 года будет означать сокращение видового разнообразия на 25%. Ученые предупреждают, что если мы не примем немедленных мер, то столкнемся с катастрофической утратой биоразнообразия. Дикие позвоночные животные уже составляют лишь 4% биомассы всех позвоночных, т. е. крайне мало по сравнению с биомассой сельскохозяйственных животных.
    We are currently observing the sixth Pleistocene-Holocene great extinction. Climate change is one of the significant factors contributing to the dramatic decline in wildlife diversity. Humanity took up the fight against climate change in 1992 by adopting the Framework Convention on Climate Change at the Rio de Janeiro Earth Summit. Unfortunately, these efforts have not produced the expected results. Rising greenhouse gas emissions will lead to the extinction of half of the species on Earth by the end of this century. Limiting the temperature increase to 2°C by 2100 will mean a 25% reduction in species diversity. For most animal species, the race against progressive climate change is difficult and even impossible to win. Scientists warn that if we do not take immediate action, we will face a catastrophic loss of biodiversity. Wild vertebrate animals already account for no more than 4% of the biomass of all vertebrates, which is dramatically lower than the biomass of farmed animals.
