The PhD project involves a macroevolutionary analysis of Crocodylia, and better understanding of the origin and time of divergencies of the clades within the group. For that purpose, some mainly analysis will be necessary such a phylogenetic reconstruction of early members of the three major crocodylian lineages through the revision of existing morphological taxon-character datasets using data collected from select key taxa from Asia, North America and particularly Europe Asian combined with published molecular data, providing a total evidence analysis of Crocodylia; and Improvement of fossil divergence dates of Paleogene extinct crocodylians using published first appearance data and the results of combined morphological-molecular phylogenetic analysis.
Baurusuchidae is a notable group of notosuchians from the Late Cretaceous of Brazil and Argentina, interpreted as being terrestrial top predators of the south of Gondwana. The group, classically identified by mediolaterally compressed rostrum, reduced and ziphodont dentition, and verticalized quadrate currently comprises ten species divided into two subgroups according to the choanal pattern: Baurusuchinae and Pissarrachampsinae. The new material, composed of a complete cranium and postcranium collect in an outcrop of the Adamantina Formation, was analyzed employing CT scan methods, in which each bone was individually segmented, allowing a high precise morphological analysis, which leads into a broader understanding of Baurusuchidae morphology and patterns. Furthermore, new characters were proposed for the phylogeny of the group, together with a proposal of a new species and discussion about the early evolution of this diversified group of notosuchians.
During the bachelor I had the opportunity to start my journey is science studying fresh water small fishes from Amazon basin, by working on taxonomy and systematics, and morphology.
