Osteohistology of Aucasaurus garridoi (Dinosauria, Theropoda, Abelisauridae): inferences on lifestyle and growth strategy
(Taylor & Francis, 2022-04)
Although osteohistology has proven to be useful to discern several palaeobiological traits and systematics in non-avian dinosaurs, the bone microstructure of several groups (e.g., abelisaurid theropods) is still poorly ...

An Early Cretaceous theropod dinosaur from Brazil sheds light on the cranial evolution of the AbelisauridaeUn dinosaure théropode du Crétacé inférieur du Brésil met en lumière l’évolution crânienne des Abelisauridae
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-10-12)
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 ...
