A ‘Terror of Tyrannosaurs’: The First Trackways of Tyrannosaurids and Evidence of Gregariousness and Pathology in Tyrannosauridae [PDF]
PLoS ONE, 2014 The skeletal record of tyrannosaurids is well-documented, whereas their footprint record is surprisingly sparse. There are only a few isolated footprints attributed to tyrannosaurids and, hitherto, no reported trackways.

Allometric growth in the frontals of the Mongolian theropod dinosaur Tarbosaurus bataar [PDF]
Acta Palaeontologica Polonica, 2022 Tarbosaurus bataar is a sister taxon of the well-studied theropod dinosaur Tyrannosaurus rex, and numerous fossils of this tyrannosaurid have been discovered in the Upper Cretaceous Nemegt Formation of Mongolia. Although specimens of different sizes of

Tyrant dinosaur evolution tracks the rise and fall of Late Cretaceous oceans. [PDF]
PLoS ONE, 2013 The Late Cretaceous (∼95-66 million years ago) western North American landmass of Laramidia displayed heightened non-marine vertebrate diversity and intracontinental regionalism relative to other latest Cretaceous Laurasian ecosystems.

A new tyrannosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Menefee Formation of New Mexico [PDF]
PeerJ, 2018 The giant tyrannosaurids were the apex predators of western North America and Asia during the close of the Cretaceous Period. Although many tyrannosaurid species are known from numerous skeletons representing multiple growth stages, the early evolution ...

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

Lower rotational inertia and larger leg muscles indicate more rapid turns in tyrannosaurids than in other large theropods [PDF]
PeerJ, 2019 Synopsis Tyrannosaurid dinosaurs had large preserved leg muscle attachments and low rotational inertia relative to their body mass, indicating that they could turn more quickly than other large theropods.
