The Gondwanian theropod families Abelisauridae and Noasauridae

Historical Biology, 1991
The theropod families Abelisauridae and Noasauridae appear closely related because of shared derived characters such as the short anterior area of the maxilla, the small or absent preantorbital fenestra, the quadrate fused to the quadratojugal, and cervical vertebrae with vestigial neural spines and hypertrophied epipophyses. The families appear linked

Osteohistology of Aucasaurus garridoi (Dinosauria, Theropoda, Abelisauridae): inferences on lifestyle and growth strategy

Historical Biology, 2022
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 documented. Here, we provide a microstructural description of different bones (a cervical epipophysis, three dorsal ribs, three ...

New abelisaurid material from the Anacleto Formation (Campanian, Upper Cretaceous) of Patagonia, Argentina, shed light on the diagnosis of the Abelisauridae (Theropoda, Ceratosauria)

Journal of South American Earth Sciences, 2021
Abstract Abelisauridae is a theropod clade with a wide distribution in the Late Cretaceous of Gondwana. Some of the best preserved abelisaurid specimens were recovered from Patagonia (Argentina) such as Skorpiovenator, Ilokelesia, Carnotaurus and Aucasaurus.

Abelisauridae Bonaparte & Novas 1985

Abelisauridae The fossil record of abelisaurids is one of the most abundant in the Kem Kem Group, being less abundant only than spinosaurids. Russell (1996) described several bone fragments, including two partial right dentaries, in addition to two partial cervical vertebrae that were attributed to an undetermined theropod, but recently were assigned ...

New brachyrostran remains (Theropoda, Abelisauridae) from La Invernada fossil site (Bajo de la Carpa Formation, Upper Cretaceous), northern Patagonia, Argentina

Cretaceous Research, 2018
Abstract Several remains of an abelisaurid theropod including a nearly complete sacral complex articulated with both ilia, the distal boot of the pubes, the furcula, teeth, and fragments of transverse processes of caudal vertebrae was discovered in the La Invernada fossil site, northern Patagonia from the Bajo de la Carpa Formation (Santonian).

Revised morphology of Pycnonemosaurus nevesi Kellner & Campos, 2002 (Theropoda: Abelisauridae) and its phylogenetic relationships

Zootaxa, 2017
Abelisaurid theropods were most abundant in the Gondwana during the Cretaceous Period. Pycnonemosaurus nevesi Kellner & Campos, 2002 was the first abelisaurid dinosaur described from the Bauru Group (Brazil, Upper Cretaceous). Nevertheless, its initial description was based on the comparison of a restricted number of remains with other abelisaurids.
