Struthiomimus sedens skeleton in the Oxford University Museum of Natural History
is a nicely preserved 3.6" long toe bone the ornithomimid dinosaur Struthiomimus sedens. Struthiomimus was long-legged, bipedal, ostrich-like dinosaurs with toothless beaks. 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.
The bone has repaired cracks through the middle and distal end, as well has minor restoration on its distal end.
