.6" Small Partial Dinosaur Phalynx - Hell Creek Formation
This is a partial phalanx bone of a small dinosaur. Based on size, it's likely from a raptor, however there is too little bone present to provid an accurate identification. It's .6" long and comes from the Hell Creek Formation of Bowman County, North Dakota. This specimen is composed of the distal head of the phalanx where it articulated with the adjacent toe bone in life.
Because of its age and sedimentary composition, the Hell Creek Formation has become one of the most paleontologically studied areas in the world. 158 genera of animals and 64 genera of plants are known from the formation and new discoveries are made frequently. In addition to Tyrannosaurs, Ceratopsids, and Hadrosaurs, the formation has yielded remains of amphibians, reptiles, lizards, snakes and turtles, fish and sharks, avian and non-avian dinosaurs, and mammals. The Hell Creek Formation gives the most complete understanding of the environment just before the Cretaceous-Paleogene extinction.
