Dromiceiomimus was a relative of Ornithomimus.Dromiceiomimus dinosaur (meaning "emu mimic") was a very fast-moving (perhaps over 40 mph = 64 km/h) bipedal dinosaur from the late Cretaceous time, about 75 to 70 million years ago.It was about 12 feet (3.6 m) long and weighed concerning 220 to 330 pounds (100 to 150 kg). Its femur (thigh bone) was 468 mm long. This ornithomimid (a bird-like theropod) had extremely long limbs and large eyes. It had a toothless, beaked mouth, and weak jaws; it may have eaten insects, eggs and some meat.
It was named by D. A. Russell in 1972 and now displayed in the natural history museum, london. The type class is D. brevitertius. Fossils of adults and juveniles have been established in Alberta, Canada. Trivia Dinosaur Comics contains a dromiceiomimus as a major character. It most probably hunted after dark, chasing small mammals and lizards through the deciduous woods.
