A New Platynotan Lizard (Parasaniwidae, Anguimorpha) from the Late Paleocene of Southern Mongolia.
Paleontological Journal 52(12): 1432â1435Â
A new lizard, Tsagansaurus nemegetensis gen. et sp. nov., from the Late Paleocene of southern Mongolia is described. It is assigned to the extinct family Parasaniwidae (Platynota, Anguimorpha). The new taxon is the latest representative of this group in the fossil record.Â

New Stage of Recovery of East European Tetrapod Community after Permian-Triassic Crisis.
Paleontological Journal 52(7): 791â795Â
New data on the taxonomic composition and comparison of the tetrapod assemblage from the Upper Sukhorechenskaya Subformation of the Buzuluk Depression of the East European Platform, previously described as âSelenocaraâSyrtosuchus fauna,â are provided. This assemblage is dated Late Induan (Dienerian) and characterizes a new stage in recovery of East European tetrapod community after the Late Permian extinction, which is intermediate between the Tupilakosaurus and Benthosuchus faunas. Beyond Eastern Europe, a similar amphibian association is known from the Anodontophora fassaensis Zone (upper part of the Wordie Creek Formation) of eastern Greenland.

On Possible Trophic Adaptations of Some Rhytidosteidae (Amphibia, Temnospondyli)
Paleontological Journal 52(12): 1412â1418Â
Temnospondyl amphibians of the family Rhytidosteidae were widespread in the Early Triassic in the Southern Hemisphere. New records in southeastern European Russia show that the type genus of the family, Rhytidosteus, was widespread in this region of Laurasia. The analysis of morphology of these specimens confined to the Late Olenekian continental deposits of the southern Cis-Urals and Buzuluk Depression and examination of accompanying ichnofossils suggest that the original structure of the skull and jaw apparatus in representatives of this genus (and probably other rhytidosteids) is connected with specific trophic adaptation, i.e., feeding on invertebrates with a rather firm armor (for example, freshwater crustaceans).

New Data on Enosuchid Anthracosauromorphs (Amphibia) of the MiddleâLate Permian of European Russia: Part 1. Morphology of Enosuchus breviceps Konzhukova, 1955.
Paleontological Journal 52(12): 1419â1427Â
Cranial morphology of the type species of the genus Enosuchus, E. breviceps Konzhukova, 1955, is reexamined in detail based on the holotype and previously undescribed specimens from the type locality (Isheevo; Tatarstan, Russia; uppermost Urzhumian). E. breviceps is distinguished from known anthracosauromorphs by the intense osteogenesis of the dermal and endocranial bones, well developed surface ornamentation, the absence of the intertemporal, expanded interorbital region, and very massive quadrate.

New Data on Early Triassic Lonchorhynchids (Amphibia, Temnospondyli) of Eastern Europe.
Paleontological Journal 52(12): 1428â1431
The family Lonchorhynchidae is considered to comprise at least two subfamilies, Cosgriffiinae (Cosgriffius Welles and a form from the Zaplavnian Horizon (Upper Induan Substage) of the Buzuluk Depression (Shishkin, 2002)) and Lonchorhynchinae (Aphaneramma Woodward, Wantzosaurus Lehman, and a form described by Damiani and Welman (2001) from the Lystrosaurus Zone of South Africa). In addition, the Lonchorhynchidae are considered to include the genera Erythrobatrachus Cosgriff et Garbutt and Stoschiosaurus SÃve-SÃderbergh, the subfamily of which is presently uncertain. A new lonchorhynchid specimen from the Zaplavnian Horizon of the Buzuluk Depression is described, the postorbital structure of which suggests that it may belong to Stoschiosaurus.
