1.4" Theropod (Raptor) Vertebrae - Hell Creek Formation

This is a well preserved vertebrae of a small theropod dinosaur, commonly referred to as a raptor. It's 1.4" wide and comes from the Hell Creek Formation of Powder River County, Montana. The proximal portions of the vertebral processes remained intact, however they broke off about 1/4" from the vertebral body.

Since the processes didn't remain intact, it's difficult to come to a conclusion regarding the exact species of theropod that this vertebrae came from.
