Gorgeous, 6.7" Struthiomimus Caudal Vertabra - Montana
Thisis a nicely preserved 6.7" long, caudal (tail) vertebra from the ornithomimid dinosaur Struthiomimus sedens. Struthiomimus was a long-legged, bipedal, ostrich-like dinosaur with a toothless beak. It was estimated that they could reach a size of approximately 13 feet in length. It's thought that due to their abundance they must have been herbivores or omnivores.
