Tooth marks

The astragalus and calcaneum are the largest bones in the ankle. The “V” shaped gouges are teeth marks of a Theropod, like a small Tyrannosaur or large raptor.  It grabbed the Hadrosaur by the ankle and pulled very hard with its front teeth leaving scratches in the ankle bone.  The Theropod probably swallowed the severed foot whole!  We do not know if this was a kill or an act of scavenging.
