Resumo: Osteoderms are dermal bony plates situated over the epiderm and covered by queratin layer. Until now are recognized at the Paleontological Site of Peirópolis three distinct crocodylomorph species, the Peirosauridae Peirosaurus termini Price, 1955 and Uberabasuchus terrificus Carvalho; Ribeiro & Ávilla, 2004 and the Trematochampsidae Itasuchus jesuinoi Price, 1955. The peirosaurids have nostrils frontally positioned within the skull and are regarded as terrestrial crocodylomorphs. The trematochampsids differently from the peirosaurids have the nostrils positioned at the dorsal portion of the skull, similar to the extant crocodiles with aquatic habits. The osteoderms morphological analysis of P. tormini, U. terrificus and I. jesuinoi corroborate, with the cranial evidences, for the terrestrial or aquatic lifestyle of these animals.

São reconhecidos até o momento no Sítio Paleontológico de Peirópolis três espécies distintas de crocodilomorfos, os Peirosauridae Peirosaurus tormini Price, 1955 e Uberabasuchus terrificus Carvalho Ribeiro Ávilla, 2004 e o Trematochampsidae Itasuchus jesuinoi Price, 1955. Os peirossaurídeos possuem narinas localizadas frontalmente no crânio e são geralmente considerados como crocodilomorfos de hábitos terrestres. Os trematocampsídeos diferentemente dos peirossaurídeos possuíam narinas localizadas na região dorsal do crânio, de modo semelhante aos crocodilos recentes de hábitos mais aquáticos. A análise morfológica dos osteodermos de P. tormini, U. terrificus e I. jesuinoi corrobora com as evidências cranianas para hábitos terrestres ou aquáticos desses animais.Universidade Federal do Rio de Janeiro2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/661610.11137/2006_2_44-53Anuário do Instituto de Geociências; Vol 29, No 2 (2006); 44-53Anuário do Instituto de Geociências; Vol 29, No 2 (2006); 44-531982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6616/5213Copyright (c) 2006 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMarinho, Thiago da SilvaRibeiro, Luiz Carlos BorgesCarvalho, Ismar de Souza2022-10-17T14:41:25Zoai:www.revistas.ufrj.br:article/6616Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2022-10-17T14:41:25Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
