The dentary of Australovenator wintonensis (Theropoda, Megaraptoridae); implications for megaraptorid dentition [PDF]

PeerJ, 2015
Megaraptorid theropods were an enigmatic group of medium-sized predatory dinosaurs, infamous for the hypertrophied claw on the first manual digit. Megaraptorid dentition is largely restricted to isolated teeth found in association with skeletal parts ...

The Late Cretaceous Diversification of Abelisauridae (Theropoda: Ceratosauria): An Overview.

, 2013
Abelisauridae is a mostly Gondwanan clade of large-bodied, basal theropods. The oldest abelisaurids were recovered from the Middle Jurassic deposits of South America, a continent that nowadays accounts more than half of named species of this clade.

Revisiting Velocisaurus unicus Bonaparte 1991 (Theropoda, Ceratosauria, Noasauridae): inferences on the Noasauridae/Abelisauridae systematic [PDF]

, 2020
In 1991, Bonaparte described Velocisaurus unicus upon an almost complete right tibia and a near complete right autopodium. He regarded this specimen a new taxon on the base of a metatarsal II and IV very mediolaterally compressed, being the metatarsal ...

Taxonomic identification of isolated theropod teeth: The case of the shed tooth crown associated with Aerosteon (Theropoda: Megaraptora) and the dentition of Abelisauridae

Cretaceous Research, 2020
Shed teeth are usually the most abundant theropod material on a dinosaur fossil site and are constantly reported in the literature. Although new quantitative techniques have emerged to identify isolated theropod teeth with better accuracy, they remain ...

Isolated theropod teeth from the Upper Cretaceous of Goias State (Brazil): northernmost occurrence of Abelisauridae from the Bauru Basin [PDF]

Journal of South American Earth Sciences
Dinosaur fossils are becoming increasingly well-known from the Bauru Basin of Brazil, and represent some of the last occurring dinosaurs in South America before the end-Cretaceous mass extinction.
