Allosaurus dinosaur suspected to be scavenging cannibal

Dinosaur-on-dinosaur dining habit revealed by scrutiny of fossil bones from Colorado site

About nine metres long, with grasping claws and a skull it used like a hatchet, Allosaurus was among the most fearsome dinosaurs of the Jurassic period. Now, it seems, the animal could also have been a cannibal.

Fossil researchers have revealed that bite marks found in a cache of dinosaur bones from the Mygatt-Moore quarry, western Colorado, were made by dinosaur-on-dinosaur dining. And the marks on Allosaurus bones had potentially been made by dinosaurs of their own kind.
