The homodont dentition and the simple shape of the teeth allow interpretation of <i>K. prima</i> as a predator with a wide trophic niche, the prey of which was determined by resources of the specific biotopes and might include both invertebrates and relatively small vertebrates. The new finds show that <i>K. prima</i> was typical for tetrapod associations of the northeast of the East European Platform, extend the stratigraphic range of the genus <i>Kotlassia</i> up to the terminal Permian (Zhukovian), and indicate that the family Kotlassiidae maintained its taxonomic diversity until the Permo–Triassic cenotic crisis, continuing to play a significant role in vertebrate communities in the time preceding it.</p>","PeriodicalId":19816,"journal":{"name":"Paleontological Journal","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141939764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
