2.7" Theropod (Struthiomimus?) Toe Bone - Montana

This is a 2.7" long proximal phalanx (toe) bone from a theropod dinosaur (Struthiomimus sedens), collected from the Hell Creek Formation of Montana. The bone preservation is exception, with some weathering of the distal end exposing the bone cells.

There is less than 1% restoration, found along the distal point of articulation.

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.
