New paper out with @val-fisch.bsky.social, @rboman.bsky.social, @narimanechatar.bsky.social and @palaeotheoryum.bsky.social 🎊 We used FEA to simulate bites in mosasaurids and polycotylids from the WIS to find clues about what they ate and how. Check it out here! doi.org/10.1111/pala...

Are you tired of people constantly overestimating body size of marine reptiles? No longer! We provide equations to estimate body size in ichthyosaurians, mosasaurids, and thalattosuchians. 1/4
New paper showing that ichthyosaurs ate vampyromorph coleoids. Did they like it ? No idea 🤷♂️ @universitedeliege.bsky.social @naturmusee.bsky.social @just-fre.bsky.social @peerj.bsky.social peerj.com/articles/19786
