Abstract

Due to the great amount of anatomical changes in those animals, the Testudines (turtles and tortoises) offer an excellent opportunity for studying the body plan evolution in vertebrates. Besides its uncertain relationships among the Amniota, the relationships among the Testudines themselves remain also poorly resolved, which makes the knowledge about the different lineages morphologies essential to better understand the evolutionary history of this group. In this sense, the integrative approach of paleontology, comparative anatomy, and embryonic development, developed by the "Evo-Devo" research program, is promissing for the acknowledge of the patterns of morphological modifications in Testudines. Among the main lineages of Testudines, Pleurodira is the least studied, but recently it has received more attention from the researchers. Additionaly, competing hypothesis of the relationships of this lineage offers different models to understand its evolutionary history. Thus, this project aims to use soft tissue anatomy, histology, embryonic development, and paleontology to better understand the origin and establishment of the morphological patterns during the evolutionary history of Pleurodira. To accomplish this I will study fossils as well as embryonic development of the different taxa of the group, focusing on two structures of great interest for functional and taxonomic considerations on the pterygoid region, the different trochlear mechanisms of the M. adductor mandibulae externus, in Pleurodira and Cryptodira (the other great lineage of Testudines), and the cavum pterygoidei, a characteristic structure on the palatal region of Pan-Podocnemidae, one of the Pleurodira lineages.
