Data associated with: Global ecomorphological restructuring of dominant marine reptiles prior to the K/Pg mass extinction

Jamie MacLaren, Rebecca Bennion, Nathalie Bardet & Valentin Fischer
Mosasaurid squamates were the dominant amniote predators in marine ecosystems during most of the Late Cretaceous. Here, we use a suite of biomechanically rooted, functionally descriptive ratios in a framework adapted from population ecology to investigate how the morphofunctional disparity of mosasaurids evolved prior to the Cretaceous-Paleogene (K/Pg) mass extinction. Our results suggest that taxonomic turnover in mosasaurid community composition from Campanian to Maastrichtian is reflected by a notable global increase in morphofunctional disparity, especially...
