Very rare femur of a Dromaeosaurid from the Hell Creek Formation. The femur belonged to a carnivorous theropod, most probably a Saurornitholestes or a Troodon that lived in the late Cretaceous in the area of ​​present-day North America. The Dromaeosaurid must have been about two feet long. He walked on its hind legs, had feathers and was warm-blooded and killes its pray with its famous sickle claw. Very special and rare femur in very good condition.
