''Ornithomimus'' had [[three]] [[toe]]s on each [[foot]], long arms and neck, but a small head. It also had [[claw]]s on each hand and foot. It had no [[teeth]] and weak [[jaw]]s, which might mean it was [[omnivorous]]. ''Ornithomimus edmonticus'' was the largest species, 12 ft (3.5 meters) long, 7 feet (2.10 meters) high and weighed about 100-150&nbsp;kg. It walked on two legs and looked slightly like an [[ostrich]], except for its long tail. There has been trouble with naming. Some speciments are put in other [[genera]], like '''''Dromiceiomimus''''' and ''[[Struthiomimus]]''.<ref>Claessens L; Loewen M. and Lavender Z. 2011.

Two adults had quill knobs on the lower arm, indicating the former presence of bird-like feather shafts. A juvenile had impressions of long fluffy feathers in the form of hair-like filaments covering the rump, legs and neck. The feather imprints were found in [[sandstone]], previously thought
