RIVERA-SYLVA, Hector E.; HONE, David W.E.  and  DODSON, Peter. Bite marks of a large theropod on an hadrosaur limb bone from Coahuila, Mexico. Bol. Soc. Geol. Mex [online]. 2012, vol.64, n.1, pp.157-161. ISSN 1405-3322.

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.
