Bite marks of a large theropod on an hadrosaur limb bone from Coahuila, Mexico

Hector E. Rivera-Sylva, David W.E. Hone

Resumen


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.
