The history of the change of the Early Triassic tetrapod communities known for the territory of Obshchii Syrt Highland includes eight successional faunal assemblages, which, in terms of the fractionality of the evolutionary stages distinguished, has no analogues in the world. Temnospondyl amphibians are the dominant elements in these tetrapod assemblages, among which the three most widely distributed groups are capitosauromorphsâcapitosaurids, benthosuchids, and trematosaurids. Remains of reptiles are much less common. The article provides brief information about the findings of rare and endemic tetrapod groups known from the Lower Triassic of Obshchii Syrt Highland. These include qantasids, lonchorhynchids, capitosaurids-selenocarines, rhytidosteids, plagiosaurs and relic anthracosaurs-chroniosuchians--from amphibians, as well as eosauropterygians, theriodonts and some genera of procolophones, prolacertiforms and thecodonts--among reptiles. The peculiarity of the systematic composition of the Early Triassic tetrapod communities of Obshchii Syrt Highland and South Cis-Urals with respect to that of the contemporary land vertebrate fauna of the more northern territories of Eastern Europe and the legitimacy of distinguishing these two areas into a distinct region characterized by specific zoogeographical connections are emphasized.

The Solvey Quarry of Bernburg is one of the most important ichnosites from the Muschelkalk of the Germanic Basin. Extensive surfaces with long chirotheriid trackways have been discovered and assigned to Chirotherium and Isochirotherium. Some undescribed step cycles from this site are analysed here and assigned to Synaptichnium isp. These footprints belong to a "thick-digit" Synaptichnium morphotype recognised at several Middle Triassic sites of Pangaea that seems to differ from the currently valid Synaptichnium ichnospecies. This is the first occurrence of Synaptichnium from this site and the only including step cycles one from the track-bearing Muschelkalk successions of N Germany and the Netherlands. A comparison between the tetrapod ichnoassociations of marginal marine and alluvial units of the Muschelkalk of the Germanic Basin reveals a similar ichnofaunal composition but different relative proportions between ichnotaxa. Rhynchosauroides and Procolophonichnium occur more often in tidal units, whereas the alluvial units show a higher abundance of chirotheriid tracks and an overall greater track diversity.

Histology of Dvinosaurus campbelli (Temnospondyli, Dvinosauria) from the Late Permian locality Gorokhovets, Vladimir Region.
Paleontological Journal (2020) 54(6): 74-82 (Russian edition)
DOI: 10.31857/S0031031X20060100
https://www.elibrary.ru/item.asp?id=43961965 The microanatomical and histological structure of the femur and hypocenters of the neotenic temnospondy amphibian Dvinosaurus campbelli from the Late Permian locality Gorokhovets, Vladimir Region, is described (Upper Vyatka, subzone Chroniosuchus paradoxus of the Scutosaurus karpinskii zone). The femoral D. campbelli is characterized by a "pachyostic" structure (dense thick periosthelial cortex in the diaphysis) and a large number (about 57) of growth marks; for the hypocenter--"osteoporotic" structure. The neotenic nature of D. campbelli is confirmed by the presence of unresorbed cartilage in bone elements in large-sized forms. Microanatomical and morphological features indicate that D. campbelli was characterized by an ambush strategy (hiding) during the hunt.
