ABSTRACT The morphology of the neurovascular canal in the jaw has been analysed in several fossil reptiles, including theropod dinosaurs. However, the details of the neurovascular canal in the dentary of theropods have not been fully elucidated. In this study, we described the well-preserved dentary of Tyrannosaurus rex, analysed the morphology of the neurovascular canal in the dentary using computed tomography techniques, and compared its distribution pattern with other dinosaurs and extant… 

The rostral neurovascular system of Tyrannosaurus rex

The study of the rostral neurovascular system using CT scanning has shed new light on phylogenetic and palaeobiological reconstructions of many extinct tetrapods. This research shows a detailed

A new theropod dinosaur from the early cretaceous (Barremian) of Cabo Espichel, Portugal: Implications for spinosaurid evolution

Iberospinus natarioi is recovered as a sister taxon of the clade formed by Baryonyx and Suchomimus, and outside Spinosaurinae when Vallibonaventrix cani is excluded from the analysis.



Complex rostral neurovascular system in a giant pliosaur

Using computed tomography scans, the extensive bifurcating neurovascular channels could be traced through the rostrum to both the teeth and the foramina on the dorsal and lateral surface of the snout of an exceptionally well-preserved pliosaur from the Kimmeridgian of Weymouth Bay.

Complex neuroanatomy in the rostrum of the Isle of Wight theropod Neovenator salerii

It is proposed that enlarged neurovascular facial canals shouldn’t be used to exclusively support a model of aquatic foraging in theropods and argue instead that an enhanced degree of facial sensitivity may have been linked with any number of alternative behavioural adaptations, among them defleshing behaviour, nest selection/maintenance or social interaction.

The endocranium of the theropod dinosaur Ceratosaurus studied with computed tomography

Based on computed tomography, Ceratosaurus is determined to have possessed a typical basal theropod endocranium and bipedal vestibular system similar to Allosaurus.

Cranial Anatomy of Erlikosaurus andrewsi (Dinosauria, Therizinosauria): New Insights Based on Digital Reconstruction

A reappraisal of the evolutionary and functional changes in the cranial skeleton as provided by this study supports prior proposals that a keratinous sheath or rhamphotheca was developed early in the evolution of Therizinosauria.

Anatomy and Ontogeny of the Mandibular Symphysis in Alligator mississippiensis

The mandibular symphysis anatomy of an ontogenetic series of Alligator mississippiensis is explored using imaging, histology, and whole mount methods to hypothesize a fused Meckel's cartilage offers stiffness in hatchling mandibles prior to the development of organized sutural ligaments and mineralized bone while offering a scaffold for somatic growth.

Quantifying neurovascular canal branching patterns reveals a shared crocodylian arrangement

Adaptations of traditional stream‐ordering methods are applied to representative structures derived from computed tomography‐scan data and this clade demonstrates a shared branching pattern that corresponds with current understanding of crocodylian sensory abilities and behaviors.

Trigeminal Nerve Morphology in Alligator mississippiensis and Its Significance for Crocodyliform Facial Sensation and Evolution

A cross‐sectional study integrating histological, morphometric, and 3D imaging analyses was conducted to identify patterns in cranial nervous and bony structures of Alligator mississippiensis, suggesting that phylogeny or somatosensory adaptations may be responsible for the variation in trigeminal ganglion and nerve size in crocodyliforms.

Endocranial Morphology of the Primitive Nodosaurid Dinosaur Pawpawsaurus campbelli from the Early Cretaceous of North America

The new information on the endocranial morphology of Pawpawsaurus adds anatomical data to the poorly understand ankylosaur paleoneurology and has potential use not only in taxonomy and phylogeny, but also in paleobiological interpretations based on the relative development of sense organs.

A new tyrannosaur with evidence for anagenesis and crocodile-like facial sensory system

A new species of Tyrannosaurid from the upper Two Medicine Formation of Montana supports the presence of a Laramidian anagenetic (ancestor-descendant) lineage of Late Cretaceous tyrannosaurids, suggesting that anagenesis could have been a widespread mechanism generating species diversity amongst dinosaurs, and perhaps beyond.
