Resumo: | Crocodyliforms compose a remarkable group of archosaurs with a fossil record extending for more than two hundred million years, with a diversity including taxa that explored terrestrial, aquatic, and semi-aquatic environments. The Late Cretaceous Bauru Group, in southeastern Brazil, harbours one of the richest crocodyliform faunas worldwide, with more than twenty described taxa. This thesis sought to redescribe and reassess two Mesoeucrocodylia from the Bauru Group, in an attempt to better understand this pattern of diversity. Barreirosuchus franciscoi, from the Adamantina Formation, was investigated based on computed tomography data and 3D reconstruction. In this process, a more accurate reassessment of its phylogenetic position was possible, with the taxon, along with Rukwasuchus yajabalajekundu, positioned along the Neouchia lineage. The second taxon, from the Marília Formation, was described as Titanochampsa iorii, also showing affinities with Neosuchia. Both target taxa show that the diversity of the Bauru Groups Mesoeucrocodylia is not restricted to notosuchians. |

O Grupo Bauru Cretáceo Superior, no sudeste do Brasil, abriga uma das mais ricas faunas de crocodiliformes do mundo, com mais de vinte táxons descritos. Esta tese buscou redescrever e reavaliar dois Mesoeucrocodylia do Grupo Bauru, na tentativa de entender melhor esse padrão de diversidade. Barreirosuchus franciscoi, da Formação Adamantina, foi investigado com base em dados de tomografia computadorizada e reconstrução 3D. Nesse processo, foi possível uma reavaliação mais precisa de sua posição filogenética, com o táxon, juntamente com Rukwasuchus yajabalajekundu, posicionado ao longo da linhagem Neouchia. O segundo táxon, da Formação Marília, foi descrito como Titanochampsa iorii, também apresentando afinidades com Neosuchia. Ambos os táxons-alvo mostram que a diversidade da Mesoeucrocodília dos Grupos Bauru não se restringe aos notosuchianos.Biblioteca Digitais de Teses e Dissertações da USPLanger, Max CardosoFacchini, Thiago Schneider2023-03-10info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/59/59139/tde-16082024-151453/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2024-10-09T15:24:03Zoai:teses.usp.br:tde-16082024-151453Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212024-10-09T15:24:03Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
