Dinosaur Bone Fragment with Theropod Tooth Marks, Patricia area, Alberta (disposition #001590)

Broken, unidentifiable dinosaur bone fragments are actually quite common in certain areas of Alberta, littering slopes and cliffs in the badlands. Occasionally, however, some of these fragments show carnivore feeding traces, evidenced by subparallel grooves and gashes in the bone. This specimen is a terrific example of either predation or scavenging tooth marks by a large theropod. Based on the size of the bone, the target animal was likely a large herbivore such as a hadrosaur or ceratopsian.

The feeding trace adds palaeobiological interest to this specimen, offering a potential record of carnivore interaction with dinosaur remains. Collected by Alberta Palaeontological Society co-founder, Harvey Negrich, this compact specimen would be a perfect addition to a dinosaur teeth collection and is, at minimum, a terrific conversation piece!
