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

Journal 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.

Presence of diminutive hadrosaurids (Dinosauria: Ornithopoda) from the Maastrichtian of the south-central Pyrenees (Spain)

Journal of Iberian Geology, 2015
En los últimos años se ha descrito una rica y diversa fauna de dinosaurios hadrosáuridos en el Cretácico Superior de los Pirineos. El reciente trabajo de campo realizado en los niveles del Maastrichtiano superior de la Formación Tremp, en el Pirineo centro-sur (provincia de Huesca, noreste de España), nos ha permitido recuperar diminutos huesos fósiles
