二叠纪-三叠纪的分界线标志着地球历史上最大规模的物种灭绝。为了了解这次严重灭绝事件的真正原因，需要在全球范围内进行多学科调查。本文对俄罗斯中部弗拉基米尔地区陆相二叠纪-三叠纪界线剖面进行了逐层取样，进行了螺甲类研究。早三叠世首次发现的分类群有：Cornia germari（Beyrich, 1857）、Euestheria gutta（Lutkevitch, 1937）、Magniestheria mangaliensis（Jones, 1862）、Palaeolimnadiopsis vilujensisVarentsov, 1955、rossolimnadiopsisnovozhilov, 1958。c的广泛分布。在日耳曼盆地的Lower Buntsandstein亚群以及匈牙利、格陵兰和西伯利亚的早三叠世沉积物中也报道过该物种，表明其具有很高的生物地层学价值。研究剖面的早三叠纪时代假设也得到了相关的图皮拉龙骨碎片的支持，这些碎片指向了早三叠纪的图皮拉龙湿陆带。
The Permian–Triassic boundary marks the greatest mass extinction in Earth's history. In order to understand the real causes of this severe extinction event, multidisciplinary investigations around the globe are required. Here, the terrestrial Permian–Triassic boundary sections in the Vladimir region, Central Russia, were sampled bed-by-bed for conchostracan study. In the Early Triassic intervals the following taxa were recognized for the first time:Cornia germari(Beyrich, 1857),Euestheria gutta(Lutkevitch, 1937),Magniestheria mangaliensis(Jones, 1862),Palaeolimnadiopsis vilujensisVarentsov, 1955, andRossolimnadiopsisNovozhilov, 1958. The wide distribution ofC. germaridemonstrates their high value for biostratigraphy, since this species was also reported from the Lower Buntsandstein Subgroup in the Germanic Basin as well as from Early Triassic deposits in Hungary, Greenland and Siberia. The assumption of an Early Triassic age of the studied sections is also supported by associatedTupilakosaurusbone fragments, which point to theTupilakosaurus wetlugensisZone in the earliest Triassic.
