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:: 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:: 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:: 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:: 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:: 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:: 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 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.
