Ontogenetic changes in the craniomandibular skeleton of the abelisaurid dinosaur Majungasaurus crenatissimus from the Late Cretaceous of Madagascar [PDF]

Acta Palaeontologica Polonica, 2016
Abelisaurid theropods were one of the most diverse groups of predatory dinosaurs in Gondwana during the Cretaceous. The group is characterized by a tall, wide skull and robust cervical region.

A NON-FURILEUSAURIAN CAUDAL VERTEBRA FROM BAJO DE LA CARPA FORMATION (SANTONIAN) AND MORPHOLOGICAL VARIATION IN THE TAIL OF ABELISAURIDAE

Publicación Electrónica de la Asociación Paleontológica Argentina, 2022
The Cerro Overo-La Invernada area in north Patagonia has provided a rich record of Cretaceous continental tetrapods in the last two decades, mainly from the Bajo de la Carpa Formation (Upper Cretaceous, Santonian).

Cautionary tales on the use of proxies to estimate body size and form of extinct animals. [PDF]

Ecol Evol
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

New insights about the anatomy of the hand of Carnotaurus sastrei (Theropoda: Abelisauridae) [PDF]

Journal of Vertebrate Paleontology, 2009
The abelisaurid theropod Carnotaurus sastrei, from the Late Cretaceous of Argentina, is characterized for the unusual presence of frontal horns and extremely abbreviated forelimbs, among other curious features. In particular, the four digit hand of Carnotaurus shows highly derived features, as recognized in previous works on this animal.

Machine learning confirms new records of maniraptoran theropods in Middle Jurassic UK microvertebrate faunas

Papers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023
Abstract Current research suggests that the initial radiation of maniraptoran theropods occurred in the Middle Jurassic, although their fossil record is known almost exclusively from the Cretaceous. However, fossils of Jurassic maniraptorans are scarce, usually consisting solely of isolated teeth, and their identifications are often disputed.

Upper Cretaceous European theropod palaeobiodiversity, palaeobiogeography and the intra‐Maastrichtian faunal turnover: new contributions from the Iberian fossil site of Laño

Papers in Palaeontology, Volume 8, Issue 1, January/February 2022., 2022
Abstract A total of 227 theropod teeth have so far been recovered from the upper Campanian Laño site (northern Iberian Peninsula). The teeth were studied for their qualitative and quantitative features. From the theropod sample found at Laño, seven morphotypes attributed to five taxa are identified: a medium to large abelisaurid (Arcovenator sp.) and ...

The first record of Abelisauridae (Theropoda: Ceratosauria) from Uruguay (Late Jurassic, Tacuarembó Formation)

Historical Biology, 2022
An incomplete albeit well preserved tooth from the Late Jurassic Tacuarembó Formation (Uruguay) shows a character combination only found in abelisaurid theropods, i.e. irregular enamel, hooked distal denticles, interdenticular sulci, lanceolate cross-sectional shape, and straight distal border.
