title: Data from: Analysing Thalattosuchia paleobiodiversity under the prism of phylogenetic comparative methods

description: Thalattosuchia is a particularly diverse group of mostly marine
 crocodylomorphs that lived during most of the Jurassic and Lower
 Cretaceous. Previous studies have sought to uncover the factors
 influencing Crocodylomorph evolution, yielding mixed results, possibly due
 to Thalattosuchia’s unique ecological niche and controversial phylogenetic
 placement among Crocodylomorph. Here, we propose a Thalattosuchia-focused
 study using phylogenetically-informed statistical analyses. First, we
 tested the phylogenetic structure of thalattosuchian survival at various
 geological transitions. We then tested the influence of biotic and abiotic
 factors on thalattosuchian diversity at the aforementioned crises.
 Finally, we tested whether diet was an additional explanatory factor. We
 found that (1) thalattosuchian diversification at the Lower-Middle
 Jurassic transition was phylogenetically structured and associated with
 signs of snout reduction possibly explained by the colonisation of emptied
 ecological niches, allowing the emergence of Machimosaurinae and
 Geosaurinae ; (2) we observed higher local temperatures for Thalattosuchia
 after the Middle-Upper Jurassic and Jurassic-Cretaceous transitions, the
 former being in accordance with most climatic literature and the latter
 being subject to more caution; Finally, (3) we corroborated previous
 studies about skull shape and found that durophageous teleosauroids tended
 to have larger body sizes than any other diet, possibly as a result of
 ecological specialization. We also found evidences of niche partitioning
 among piscivorous and macrophageous metriorhynchoids that is observable by
 a size range extension.
