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:
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:
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.

Conjectures about the Cretaceous and post−Cretaceous vertebrate faunas of Madagascar are generally based on the fact that these faunas display similarities to those of South America, and that Africa lacks taxa that are common to Madagascar and South America. In order to account for this distribution, two ways of dispersal bypassing Africa have been proposed.

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.

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.

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.

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”.

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:
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.
