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.

The Hell Creek Formation

Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
