Abstract

The brain morphology and the topography of the cranial nerves on an endocranial mold of the theropod dinosaur Tarbosaurus bataar (Tyrannosauridae) are examined. The brain of this dinosaur was constructed based on the reptile archetype, with a well-developed specialized olfactory analyzer. In terms of development, the visual centers were superseded not only by the olfactory centers, but also by the auditory centers. Comparative analysis of the brain structure of Tarbosaurus and Tyrannosaurus shows clear distinctions in the topography of roots of the accessory and trigeminal nerves.
