Última Oology and the evolution of thermophysiology in saurischian dinosaurs: homeotherm and endotherm deinonychosaurians? Pap. Avulsos de Zool. (São Paulo) Grellet-Tinner,Gerald. The origin of avian endothermy is a long-held question the answer of which cannot be provided by first level observations. Oological and reproductive characters have collectively provided a new source of data useful for phylogenetic analyses and paleobiological inferences. In addition, the observations of reproductive and oological evolutionary trends in saurischian dinosaurs lead to the interpretation that not only, the thermophysiology of these dinosaurs progressively became more avian-like but after re-examination allows to infer that deinonychosaurians represented here by three troodontids and one dromaeosaurid might already have developed an avian-like endothermy, thus predating the rise of avians. These results based on reproductive traits are... Tipo: Info:eu-repo/semantics/article Palavras-chave: Endothermy; Avian; Troodontid theropod dinosaurs; Oology; Reproductive behaviors.

Avulsos de Zool. (São Paulo) Grellet-Tinner,Gerald; Zaher,Hussam. The taxonomically (titanosaurid) identified eggs and eggshells of Auca Mahuevo (Patagonia, Argentina) provide an opportunity to compare and identify orphan megaloolithid eggs found elsewhere. Previous investigation determined that the oological material from Neuquén (Megaloolithus patagonicus) and Peru (M. pseudomamillare) are related to titanosaurid dinosaurs. Examination of an egg and several (megaloolithid) eggshell fragments from the Upper Cretaceous Marilia Formation strongly suggests, as oological characters are at least genus specific, that the same group of titanosaur dinosaurs, which lived in the Neuquén Basin during the Late Campanian, were also present and reproducing in the Cretaceous Bauru Basin (Brazil). Furthermore, it has been suggested... Tipo: Info:eu-repo/semantics/article Palavras-chave: Titanosaurid eggs; Bauru Basin; Auca Mahuevo; Eggshell structure; Dinosaur paleobiology.
