1.8" Partial Dinosaur (Struthiomimus?) Metatarsal - Montna
This is a partial metatarsal (foot) bone of an ornithomimid theropod dinosaur (Struthiomimus sedens?), collected from the Hell Creek Formation in Montana. It is the distal-most epiphysis of the bone.
It can be difficult to distinguish species from an isolated bone such as this. While there are multiple Ornithomimids that come out of the Hell Creek Formation, this deposit produces significantly more Struthiomimus material than Ornithomimus, indicating that this is very likely from Struthiomimus.

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.
