The Paranasal Air Sinuses of Predatory and Armored Dinosaurs (Archosauria: Theropoda and Ankylosauria) and Their Contribution to Cephalic Structure [PDF]

open access: yesThe Anatomical Record, 2008
AbstractThe paranasal air sinuses and nasal cavities were studied along with other cephalic spaces (brain cavity, paratympanic sinuses) in certain dinosaurs via CT scanning and 3D visualization to document the anatomy and examine the contribution of the sinuses to the morphological organization of the head as a whole.

A proxy for brain‐to‐endocranial cavity index in non‐neornithean dinosaurs and other extinct archosaurs

open access: yesJournal of Comparative Neurology, Volume 532, Issue 3, March 2024.
Illustration of the endocranial doming, which can provide a proxy for the brain‐to‐endocranial cavity index, using the endocast of an adult of the iguanodont dinosaur Proa valdearinnoensis as an example. Abstract Although the brain fills nearly the entire cranial cavity in birds, it can occupy a small portion of it in crocodilians.
