ABSTRACT Carnotaurus sastrei is a large abelisaurid dinosaur from the Upper Cretaceous of Patagonia. Its remains include an almost complete skeleton with a well-preserved skull and braincase. Because relatively few abelisaurid braincases are known, the description of the Carnotaurus braincase is important for understanding the variability of this complex structure within the clade. Carnotaurus exhibits traits that characterize the abelisaurid basicranium, such as a well-developed preotic… Expand

Braincases of abelisaurid theropods from the Upper Cretaceous of north Patagonia
The braincases of the abelisaurid theropod dinosaurs Abelisaurus comahuensis and Aucasaurus garridoi are described and compared. These two taxa share the presence of a floccular recess that is… Expand
The skull of Carnotaurus sastrei Bonaparte 1985 revisited: insights from craniofacial bones, palate and lower jaw
ABSTRACT Carnotaurus sastrei is perhaps the most iconic representative of the Abelisauridae family. It is known by a fairly complete specimen, recovered from Upper Cretaceous beds of southern… Expand
Novel information on the endocranial morphology of the abelisaurid theropod Carnotaurus sastrei
TLDR
The endocranial morphology confirms that abelisaurids share an overall conformation of the brain and inner ear, and the olfactory acuity of Carnotaurus resembles that reported for other abel isaurids, suggesting that the sense of smell had an important role. Expand
Braincase Anatomy of Pterodaustro guinazui, Pterodactyloid Pterosaur from the Lower Cretaceous Of Argentina
ABSTRACT The braincase anatomy of pterosaurs is poorly known because this region of the skull is rarely preserved, particularly in basal pterodactyloid pterosaurs (Archaeopterodactyloidea). We… Expand
The Braincase of the Theropod Dinosaur Murusraptor: Osteology, Neuroanatomy and Comments on the Paleobiological Implications of Certain Endocranial Features
Abstract. A detailed description of the neuroanatomy of Murusraptor barrosaensis—a mid-sized non-maniraptoran theropod from the Late Cretaceous of north Patagonia—is based on the exceptionally… Expand
A new medium-sized abelisaurid (Theropoda, Dinosauria) from the late cretaceous (Maastrichtian) Allen Formation of Northern Patagonia, Argentina
Abstract Abelisaurid theropods are well known in Cretaceous beds along South America, particularly Patagonia. However, the record of latest Cretaceous abelisauroids is still far from satisfactory.… Expand
Braincase Anatomy of the Basal Theropod Sinosaurus from the Early Jurassic of China
The neuroanatomy of the mid-sized theropod Sinosaurus triassicus from the Lower Jurassic Lufeng Formation, Lufeng Basin in Yunnan Province, China was studied using X-ray computed tomography. The… Expand
A New Furileusaurian Abelisaurid from la Invernada (Upper Cretaceous, Santonian, Bajo de la Carpa Formation), Northern Patagonia, Argentina
ABSTRACT Abelisaurids are among the most abundant and diverse Patagonian Late Cretaceous theropods. Here, we present a new furileusaurian abelisaurid, Llukalkan aliocranianus gen. et sp. nov.,… Expand
Small-sized abelisaurid (Theropoda: Ceratosauria) remains from the Upper Cretaceous of northwest Patagonia, Argentina
Abstract A new abelisaurid theropod from the Cenomanian of Candeleros Formation (Neuquen Province, NW Patagonia, Argentina) is described. It includes an isolated frontal, partial pelvis, two fused… Expand
New furileusaurian remains from la invernada (northern Patagonia, Argentina): A site of unusual abelisaurids abundance
TLDR
These findings, added to the previous ones, not only reveal the abundance of abelisaurids in this geographical area, but also the variety of morphotypes that coexisted during the middle of the Upper Cretaceous, at least in the north of Argentine Patagonia. Expand

TLDR
Comparison of the new skull with the poorly preserved skull of the holotype of Oviraptor philoceratops demonstrates that the braincase and palate of the latter are similar to those of other oviraptorids, suggesting it may be the most basal ovIRaptorid. Expand
