Ornithomimus


Ornithomimus

▪ dinosaur genus
 ostrichlike dinosaurs (dinosaur) found as fossils in Mongolian, European, and North American deposits dating from 65 million to 125 million years ago (Early and Late Cretaceous Periods).

      Ornithomimus was about 3.5 metres (11.5 feet) long, and, although it was a theropod dinosaur, it was likely omnivorous. Its name means “bird mimic,” and, like most other members of its subgroup (Ornithomimidae), it was toothless and had beaklike jaws. The small, thin-boned skull had a large brain cavity. Its three fingers were unusual among dinosaurs in that they were all approximately the same length. Ornithomimus's legs were very long, especially its foot bones (metatarsals (metatarsal)). The legs and feet, along with its toothless beak and long neck, provide a superficial resemblance to the living ostrich. A related ornithomimid is so ostrichlike that its name means “ostrich-mimic” (see Struthiomimus). Ornithomimidae also includes small forms such as Pelecanimimus, larger ones such as Garudimimus and Harpymimus, and the giant Deinocheirus, known only from a 2.5-metre shoulder girdle and forelimb from the Late Cretaceous of Mongolia.
