4.3" Theropod Scapula (Shoulder Bone) - Montana

This is a 4.3" long, fossil Scapula (shoulder blade) of a theropod dinosaur, from the Hell Creek Formation, Montana. It is likely the scapula of a species of Raptor. There are multiple species of raptors described from this formation and assigning isolated bones to a species or genus is often guesswork. There is crack repair on this bone.
