ornithomimids
Ornithomimids were a group of fast-running dinosaurs that lived during the Late Cretaceous period. They are known for their bird-like features, including long legs, a slender body, and a long neck. These dinosaurs were primarily herbivorous, feeding on plants and possibly small animals, and they had a beak-like mouth without teeth.
Fossils of ornithomimids have been found in various locations, including North America and Asia. Their lightweight build and long limbs suggest they were well-adapted for speed, allowing them to escape predators. Ornithomimids are often compared to modern ostriches due to their similar body structure and lifestyle.
