A reassessment of the taxonomic validity of Dynamoterror dynastes (Theropoda: Tyrannosauridae)
Zoodiversity, 2020 Associated fragmentary materials of tyrannosaurid theropod, Dynamoterror dynastes McDonald et al., 2018, were reported in 2018 from the Upper Cretaceous Menefee Formation of New Mexico. However, two originally proposed autapomorphies (i.e. prefrontonasal

Reconsidering the Avian Nature of the Oviraptorosaur Brain (Dinosauria: Theropoda). [PDF]
PLoS ONE, 2014 The high degree of encephalization characterizing modern birds is the product of a long evolutionary history, our understanding of which is still largely in its infancy.

New perspectives on body size and shape evolution in dinosaurs. [PDF]
Biol Rev Camb Philos SocABSTRACT Diversity in the body shapes and sizes of dinosaurs was foundational to their widespread success during the Mesozoic era. The ability to quantify body size and form reliably is therefore critical to the study of dinosaur biology and evolution.

Statistical evaluation of character support reveals the instability of higher-level dinosaur phylogeny [PDF]
Scientific Reports, 2023 The interrelationships of the three major dinosaur clades (Theropoda, Sauropodomorpha, and Ornithischia) have come under increased scrutiny following the recovery of conflicting phylogenies by a large new character matrix and its extensively modified ...

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 ...
