The ornithomimids are coelurosaurians, and the most derived family of Ornithomimosauria. They lived during the Cretaceous Period. Ornithomimids ("bird mimics") are ostrich-like, with long, skinny legs and necks, and were perhaps the fastest-running dinosaurs. The ornithomimids in Dinosaur King appear in Normal Moves, but one was made into a TCG-Wind Dinosaur, so this is likely the group's native Element.
