Resumo: Sacisaurus agudoensis is the only silesaurid known from the Triassic beds of the Santa Maria Supersequence and the correlation of its type locality to the other Triassic deposits of south Brazil has always been controversial. In an attempt to improve this, a handful of dinosaur and cynodont remains found associated to S. agudoensis are here described and compared. The anatomy of the sauropodomorph is more similar to that of Norian forms such as Pantydraco caducus and Unaysaurus tolentinoi than to that of Carnian taxa such as Saturnalia tupiniquim and Pampadromaeus barberenai. The cynodonts recovered based on isolated teeth include a brasilodontid and a Riograndia-like form. This assemblage is consistent with a Norian age, as is also suggested by local stratigraphic correlation, which positions the site in the Caturrita Formation.

Numa tentativa para melhorar isto, são aqui descritos alguns restos de dinossauros e cinodontes encontrados associados a S. agudoensis e comparado. A anatomia do sauropodomorfo é mais semelhante à das formas Norian, como Pantydraco caducus e Unaysaurus tolentinoi do que aos táxons Carnianos como Saturnalia tupiniquim e Pampadromaeus barberenai. Os cinodontes recuperados com base em dentes isolados incluem um brasilodontídeo e uma forma do tipo Riograndia. Esta montagem é consistente com uma idade Norian, como também é sugerido pela correlação estratigráfica local, que posiciona o sítio no Formação Caturrita.porUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOLOGIAActa palaeontologica polonicaDinosauriaSauropodomorphaDinosauriformesCynodontiaFormação CaturritaTriássicoNorianNew sauropodomorph and cynodont remains from the Late Triassic Sacisaurus site in southern Brazil and its stratigraphic position in the Norian Caturrita FormationNovos restos de sauropodomorfos e cinodontes do sítio Sacisaurus do Triássico Superior no sul do Brasil e sua posição estratigráfica na Formação Norian Caturritainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleJúlio MarsolaJonathas de Souza Bittencourt RodriguesÁtila da RosaAgustin MartinelliAna Maria RibeiroJorge FerigoloMax Langerapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
