恐竜説明：
Struthiomimus was a smaller version of Gailimimus and, again, resembles a featherless ostrich. It had a small head with a toothless beak. The neck and tail were very long. The skull was lightly built, with huge openings for the eyes. Struthiomimus had very good eyesight and was in all likelihood quite intelligent. It fed on insects, small reptiles and probably plants.
Struthiomimus's large eyes may have given it stereoscopic vision, so that it had a three dimensional view of the world. This would have allowed the 'Ostrich Mimic' to judge distances accurately and to hunt at dusk or even during the night.
Like many other dinosaurs, Struthiomimus had small stones in its gizzard (the part of a bird's stomach which grinds food in this case, tough plant material). It is known from Alberta in western Canada and, along with 30 or so other dinosaurs, is part of one of the world's best exhibitions at the Tyrrell Museum in Drumheller.
