Struthiomimus was a long-legged, ostrich-like dinosaur of the ornithomimid family. It lived in the area that is now Alberta, Canada, during the late Cretaceous, approximately 75 to 65 million years ago.
Description [change]
Struthiomimus had a typical build and skeletal structure for an ornithomimid, differing from genera like Ornithomimus and Dromiceiomimus in proportions and anatomical details.[1] It is known from several skeletons and skulls,[2] and its size is estimated as about 4.3 metres (14 ft) long and 1.4 metres (4.6 ft) tall at the hips, with a weight of around 150 kilograms (330 lb).[1] As with other ornithomimids, it had a small slender head on a long neck (which made up about 40% of the length of the body in front of the hips).[2] Its eyes were large and its jaws were toothless. Its vertebral column had ten neck vertebrae, thirteen back vertebrae, six hip vertebrae, and about thirty-five tail vertebrae.[3] The tail was stiff and was probably used for balance.[4]
