Rayososaurus (Sauropoda, Diplodocoidea) no Meso-Cretáceo do norte-nordeste brasileiro

Abstract

RESUMO – Os depositos continentais cenomanianos da Formacao Alcântara no Estado do Maranhao, Nordeste do Brasil, incluem uma paleocomunidade reunindo plantas, dinossauros, crocodilos e peixes. Dentes isolados e fragmentos osseos, principalmente centros vertebrais caudais, sao os elementos mais comumente identificaveis. A comparacao com um esqueleto articulado, quase completo de Neuquen na Patagonia argentina, e com dados publicados revelou que grande parte dos centros vertebrais caudais provenientes da Formacao Alcântara estao relacionados a Rayososaurus tessonei (= Rebbachisaurus tessonei). Alguns destes centros tambem mostram similaridades com centros de “Rebbachisaurus tamesnensis” da Africa do norte. Apesar do confuso status taxonomico destas formas impedir uma identificacao especifica para a forma brasileira, esta ocorrencia estabelece mais um elo entre as faunas dinossaurianas da Patagonia, do Nordeste brasileiro e do Saara. Palavras-chave: dinossauros, Rayososaurus, Formacao Alcântara, Cenomaniano, Cretaceo.
