An Early Cretaceous theropod dinosaur from Brazil sheds light on the cranial evolution of the Abelisauridae [PDF]
Comptes Rendus Palevol, 2020 Abelisaurid theropods dominated the predator role across Gondwana during the Late Cretaceous. They are characterized by highly reduced forelimbs and one of the most specialized cranial morphologies among carnivorous dinosaurs, exemplified by a broad skull, short rostrum, high occipital region, and highly kinetic intramandibular joint, suggestive of a ...

The geometry of taking flight: Limb morphometrics in Mesozoic theropods
Journal of Morphology, Volume 276, Issue 2, Page 152-166, February 2015., 2015 ABSTRACT Theropoda was one of the most successful dinosaurian clades during the Mesozoic and has remained a dominant component of faunas throughout the Cenozoic, with nearly 10,000 extant representatives. The discovery of Archaeopteryx provides evidence that avian theropods evolved at least 155 million years ago and that more than half of the tenure of
