We describe the basal sauropodomorph Eoraptor lunensis, based on the nearly complete
holotypic skeleton and referred specimens, all of which were discovered in the Cancha de …

Non-avian theropod dinosaurs attained large body sizes, monopolising terrestrial apex
predator niches in the Jurassic–Cretaceous. From the Middle Jurassic onwards …

Three partial skeletons allow a nearly complete description of the sacrum, pelvic girdle, and
