Biotic and abiotic factors and the phylogenetic structure of extinction in the evolution of Tethysuchia

Crocodylomorpha is a large and diverse clade with a long evolutionary history now restricted to modern crocodylians. Tethysuchia is a less-inclusive clade of semi-amphibious taxa that crossed two biological crises: the second Oceanic Anoxic Event (OAE 2) and the Cretaceous/Paleogene (K/Pg) Crisis. Numerous studies have sought to find the driving factors explaining crocodylomorph evolution producing contradictory conclusions. Studies of included groups may be useful. Here, we study factors driving tethysuchian evolution using phylogenetically informed statistical analyses. First, we tested the phylogenetic structure of tethysuchian extinction at the OAE 2 and K/Pg crises. We then used phylogenetic comparative methods to test the influence of intrinsic (body size, snout proportion) and extrinsic (temperature, paleolatitude) factors on the evolution of tethysuchian diversity at the OAE 2 and the K/Pg crises. Finally, we tested whether temperature influenced the evolution of body size. We c..., , , # Biotic and abiotic factors and the phylogenetic structure of extinction in the evolution of Tethysuchia
