The braincase region of tyrannosaurs was investigated to provide insights on anatomical
attributes relevant to inferences of sensory biology and behavior. CT scanning focused on …

The Ankylosauria is a group of herbivorous, quadrupedal, armoured dinosaurs subdivided
into at least two major clades, the Ankylosauridae and the Nodosauridae. The most derived …

Metabolic heat production in archosaurs has played an important role in their evolutionary
radiation during the Mesozoic, and their ancestral metabolic condition has long been a …

Jaw muscles are key components of the head and critical to testing hypotheses of soft‐tissue
homology, skull function, and evolution. Dinosaurs evolved an extraordinary diversity of …

The rapidly expanding interest in, and availability of, digital tomography data to visualize
casts of the vertebrate endocranial cavity housing the brain (endocasts) presents new …

The monophyly of Oviraptoridae, a group of theropod dinosaurs, which share a uniquely
bizarre morphology, has never been called into question due in large part to their unusual …

Enantiornithines are the most speciose avian clade in the Mesozoic, with a fossil record that
nearly spans the Cretaceous; however, with less than half of known taxa preserving skull …

Ornithischian dinosaurs exhibited a diversity of ecologies, locomotory modes, and social
structures, making them an ideal clade in which to study the evolution of neuroanatomy and …

The attachments of jaw muscles are typically implicated in the evolution and shape of the
dorsotemporal fenestra on the skull roof of amniotes. However, the dorsotemporal fenestrae …

ABSTRACT A juvenile skull of the tyrannosaurid Tarbosaurus bataar found in the Bugin
