Dromiceiomimus was an dinosaur that lived in North America during the late
between about 80 and 65 million years ago.
Dromiceiomimus was about 12 feet (3.5 meters) long, and is believed to have weighed
around 220 to 330 pounds (100 to 150 kilograms). It is thought to have been a fast-runner
like its close relative, Struthiomimus.
It also seems to have good vision, and may well have been nocturnal.
As with Struthiomimus,
there has been some debate about what Dromiceiomimus would have eaten.
Dromiceiomimus is often considered to have been an omnivore. It is diet may have consisted of
small lizards and mammals, eggs, insects, and fruit. It has been suggested (most noteably by the paleontologist
Dale A. Russell) that Dromiceiomimus may have been entirely carnivorous, but the animal does seem to have
some features would have suited a party herbivorous lifestyle.
Dromiceiomimus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Dromiceiomimus was not closely related to lizards, it did have similarly shaped pelvic bones.
Dromiceiomimus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Dromiceiomimus was not itself an ancestor of birds).
Dromiceiomimus lived between about 80 million years ago and 65 million years ago, during the late Cretaceous period.
Dromiceiomimus was a omnivore (ate both meat and plants).
Dromiceiomimus is usually thought of as an omnivore, as the animal's body shape suggests it would have been suited to a part herbivorous (plant-eating) lifestyle. However, it has also been argued that Dromiceiomimus may have been entirely carnivorous (meat-eating).
Dromiceiomimus was about 14 feet (4.3 meters) long, and about 4½ (1.4 meters) tall at the hips.
Dromiceiomimus weighed about 330 pounds (150 kilograms).
