Ontogenetic Changes in Endocranial Anatomy in Gorgosaurus libratus (Theropoda: Tyrannosauridae) Provide Insight Into the Evolution of the Tyrannosauroid Endocranium. [PDF]
J Comp NeurolChanges through growth (ontogenetic) in the braincase of the eutyrannosaurian tyrannosauroid Gorgosaurus libratus are discussed. Most notably, brain cavity endocasts of immature Gorgosaurus are found to more clearly show details of the brain morphology than more mature individuals, a finding that has implications for improving dinosaur paleoneurology ...

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

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

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.

Estimation of maximum body size in fossil species: A case study using Tyrannosaurus rex [PDF]
Ecology and EvolutionAmong extant species, the ability to sample the extremes of body size—one of the most useful predictors of an individual's ecology—is highly unlikely. This improbability is further exaggerated when sampling the already incomplete fossil record.

Geology and taphonomy of a unique tyrannosaurid bonebed from the upper Campanian Kaiparowits Formation of southern Utah: implications for tyrannosaurid gregariousness [PDF]
PeerJ, 2021 Tyrannosaurids are hypothesized to be gregarious, possibly parasocial carnivores engaging in cooperative hunting and extended parental care. A tyrannosaurid (cf.

Two braincases of Daspletosaurus (Theropoda: Tyrannosauridae): anatomy and comparison1 [PDF]
, 2021 For sheer complexity, braincases are generally considered anatomically conservative. However, recent research on the braincases of tyrannosaurids have revealed extensive morphological variations.
