3.8" Ornithomimid (Struthiomimus) Toe Bone - Montana

This is a nicely preserved, 3.8" long, proximal phalanx (toe) from the ornithomimid theropod, Struthiomimus sedens, collected from the Hell Creek Formation of Montana. Some cortical bone is preserved along the dorsal surface of the bone.

Some spots of minor gap fill restoration can be found throughout the diaphysis of the bone. There is some significant restoration to the proximal end of the bone.

Struthiomimus were long-legged, bipedal, ostrich-like dinosaurs with toothless beaks. They reached estimated sizes of approximately 13 feet in length. It is thought that due to their abundance, they must have been herbivores or omnivores.

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.
