Struthiomimus (name meaning "Ostrich Mimic") is a genus of omnivorous ornithomimid dinosaur that originated during the Late Cretaceous period in what is now North America. A relative of Gallimimus, this omnivore is one of the more common small dinosaurs.
Thought to have been extinct for 65 million years, there are still flocks that remain alive on Primeval Island. In fact, they are among the most common Ornithomimid there, alongside Ornithomimus and Gallimimus.
