Current research suggests that Struthiomimus was a fast moving herbivorous creature of average size...according to your answers so are you!
Struthiomimus was built for speed, with long muscular hind legs and a stiff tail so it could balance and make quick turns. It didn't have any teeth though. Scientists think that it may have eaten leaves and fruits, collecting them with a horny beak, much like a turtle's.
