Abstract Currently the most studied group of Theropoda belongs to the clade Tyrannosauroidea that was originated from Late Jurassic, was the principal group of predators of North hemisphere during the Cretaceous and is composed by two families: Proceratosauridae and Tyrannosauridae. The first family is represented by reduced size animals and elaborate cranial crests, while the second is represented by bigger animals, with big skulls and reduced fore limbs. Other diverse group of Theropoda is the Ceratosauria that according the most recents analysis, this group originated from Late Jurassic and the more derivates forms was the principal predators of South hemisphere. Ceratosauria is composed by basal shapes + Abelisauroidea. Basal Ceratosauria were smaller than the derivates shapes and had longer fore limbs. The derivates shapes show highs and shorts skulls and reduced forelimbs. Since both clade (Tyrannosauroidea and Ceratosauria) became the top predators of their hemispheres this project aims to assess and describe, quantitatively, the morphological similarities and differences in their different morpho-functional complex using morphometric techniques, reconstruction of ancestral characters and character evolution along the phylogeny in order to investigate whether there is coordinated evolution (correlated) of the various complex morphological and if this development is similar between groups. The data to be analyzed will be obtained through digital photographs and a 3D scanner. (AU) | |
