  Abstract

We describe theropod bite marks on the tibia of a hadrosaurine ornithopod recovered northwest of Coahuila, Mexico. Based on the size and shape of the bites, these marks are attributed to a tyrannosaurine. The finding provides support for recent hypotheses on theropod feeding behavior and palaeoecology.

Keywords: Tyrannosaurine, palaeoecology, feeding, behavior, Ornithischian.
