Abstract

Variations previously reported for the endocast of Triceratops represent poorly preserved, incomplete or misidentified material as well as questionable interpretations. A new endocranial cast of Triceratops horridus produced from a complete, undistorted cranium provides new knowledge of the brain structure. The present endocast has the 12 main nerves, some with unreported branches. Those nerves have been extended as far as their tracks could be followed within the walls of the braincase. This specimen is arguably the most informative cast available including unknown and inadequately described aspects of the brain of Triceratops.
