Ornithomimus differs from other ornithomimids, like Struthiomimus and Gallimimus, in having very slender, straight hand and foot claws and fingers of related lengths. It had sprinted along with its body parallel to ground, balanced by its long and out-stretched tail and it was kept stiff by strong ligaments that lashed the vertebrae to form a rigid structure. Its neck have curved upward in a long bend and holding the head for good visibility by means of large eyes. The arms of Ornithomimus have dangled above the ground with dexterous and clawed fingers which is held ready to grasp potential food. It was bipedal and resembled an ostrich, which is 12 ft (3.5 meters) long, 7 feet (2.10 meters) high and weighed around 100–150 kg. It also seems to have feeding habits more like that of a duck than an ostrich. Like other ornithomimids, it may also eat leaves, fruits, insects and other small animals like lizards and mammals and it even raided the nests of other dinosaurs and eaten their eggs, pecking through shells with its horny beak. It might run away at a speed of upto 30mph/50 kmph. Ornithomimus was first discovered by J.B.Hatcher in Denver Colorado. Its now displayed at the Royal Ontario Museum, Toronto.
