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.

Hindlimb biomechanics of Lagosuchus talampayensis (Archosauria, Dinosauriformes), with comments on skeletal morphology

Journal of Anatomy, Volume 246, Issue 6, Page 948-973, June 2025.
The study constructs a 3D whole‐body biomechanical model of the Late Triassic archosaurian reptile Lagosuchus talampayensis, which includes reconstructions of the hindlimb musculature. The process of constructing the model revealed that numerous limb bones curated with the main specimens are from other, as‐yet‐undetermined archosaurs.

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs

The Anatomical Record, Volume 308, Issue 5, Page 1349-1368, May 2025.
Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.

Birdlike growth and mixed-age flocks in avimimids (Theropoda, Oviraptorosauria) [PDF]

Scientific Reports, 2019
AbstractAvimimids were unusual, birdlike oviraptorosaurs from the Late Cretaceous of Asia. Initially enigmatic, new information has ameliorated the understanding of their anatomy, phylogenetic position, and behaviour. A monodominant bonebed from the Nemegt Formation of Mongolia showed that some avimimids were gregarious, but the site is unusual in the ...

Cancellous bone and theropod dinosaur locomotion. Part I—an examination of cancellous bone architecture in the hindlimb bones of theropods [PDF]

, 2018
This paper is the first of a three-part series that investigates the architecture of cancellous (‘spongy’) bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous bone architectural patterns to infer locomotor biomechanics in extinct ...

How smart was T. rex? Testing claims of exceptional cognition in dinosaurs and the application of neuron count estimates in palaeontological research

The Anatomical Record, Volume 307, Issue 12, Page 3685-3716, December 2024.
Abstract Recent years have seen increasing scientific interest in whether neuron counts can act as correlates of diverse biological phenomena. Lately, Herculano‐Houzel (2023) argued that fossil endocasts and comparative neurological data from extant sauropsids allow to reconstruct telencephalic neuron counts in Mesozoic dinosaurs and pterosaurs, which ...
