Abstract

Crocodylians are one of the oldest extant lineages on the planet, having originated towards the late Triassic over 200 Ma. Their large fossil diversity stands in contrast to only 23 living species and as such provides a rich source for studies of phylogeny, biogeography and disparity changes throughout time. This project will examine the evolution of a group of both extant and fossil crocodiles, the Neosuchia, since their emergence in the Cretaceous (145 Ma) using both morphological and molecular data for a comprehensive new phylogeny. Enhanced methods in morphometrics such as CT-scanning will improve our knowledge of disparity throughout time and allow conclusions about the palaeoecology of Neosuchia. As such the analysis will facilitate the evaluation of responses of the lineage to changing climate in the past and present. The new data gathered will also help and clarify the issue of homoplastic characters and their influences on the tree and help resolve the current disagreements between morphological and molecular data sets, as well as shine light on biogeographical questions concerning the distribution patterns of both extant and fossil crocodylian taxa.
