Description: Diagram showing all the known Dinosauria from the Hell Creek Formation, including the indeterminate Azhdarchid[1] and aquatic reptiles: Champsosaurus and an indeterminate Mosasaur known from fragmentary remains[2]. Obviously, there is more fauna in this formation, such as turtles, alligators, crocodiles, mammals and invertebrates, the depicted animals are the most notorius.[3][4][5][6]NOTE: This formation is geographically close to the North Horn Formation, in wich, the remains of Alamosaurus have been found, the occurences beetwen Alamosaurus and this fauna are indeed very possible, however, Alamosaurus was not included in the diagram since the remains of this animal have not been found in Hell Creek.
