Braincase anatomy and palaeoneurology of Venetoraptor gassenae, a lagerpetid pterosauromorph from the Late Triassic of southern Brazil

open access: yesPalaeontology, Volume 69, Issue 2, 2026.
Abstract There is a growing consensus that pterosaurs and the flightless Lagerpetidae are closely related. This relationship is supported by apomorphies throughout the skeleton, including endocranial character states such as a well‐developed floccular fossa and a tall anterior semicircular canal. Our knowledge of lagerpetid anatomy has been improved by

Eggshell geochemistry reveals ancestral metabolic thermoregulation in Dinosauria

open access: yesScience Advances, 2020
All major groups of Mesozoic dinosaurs exhibited metabolically mediated thermoregulation based on clumped isotopes in eggshells. Studying the origin of avian thermoregulation is complicated by a lack of reliable methods for measuring body temperatures in
