This is a fossil thoracic vertebra bone from the large, swift meat-eating dinosaur, Deltadromeus agilis. It was found many years ago in the Cretaceous Kem Kem Red Bed deposits of North Africa. It is in rare condition with an intact neural canal for where the spinal cord once passed through. The only parts missing are the transverse and dorsal processes. Very rare and for the price of a nice tooth which is far more common than an actual bone from the dinosaur!
