| contents | Description of a sauropod dinosaur braincase (Titanosauridae) from the late Cretaceous Rio Colorado subgroup, Patagonia Alexander W. Kellner Jorge O. Calvo Multidisciplinaria (Ciencias Naturales y Exactas) braincase Argentina Patagonia Titanosauridae Late Cretaceous The fossil record of cranial material from titanosaurid sauropods is very poor and no complete skull hasbeen described so far. Here we describe a new braincase (MUCPv-334) that was recovered from reddishsandstones of the Rio Colorado Subgroup (Late Cretaceous) of the region of Bajo del Añelo, approximately 20km north of the town Añelo (Neuquén Province, Argentina). This specimen is attributed to the Titanosauridaebased on the ventrally projected basipterygoid processes, a common condition shared by other titanosaurids.The robustness of MUCPv-334 together with an unusually expanded crista prootica and the presence of ananterior prolongation of the parasphenoid reaching the basal tubera were not reported in other members ofthe Titanosauridae, indicating a larger diversity in the braincase morphology of this sauropod clade thanpreviously thought. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778115 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.78 |
