An omnivorous dinosaur, it had a long neck, stood on two long legs, with a small head and a beak; it looked kind of like an ostrich. In fact, its name means ‘ostrich mimic’ because of how it looked and how it probably moved. Remember in Jurassic Park, how that herd of fast running dinosaurs about as tall as a person ran past Lex, Tim, and Dr. Grant in that field? Those were Gallimimus’, very much like Struthiomimus’. Utilizing speed as a means of defense, they could sprint about 25 miles (40km) per hour to outrun predators. They traveled in groups for the safety in numbers factor. Struthiomimus had a varied diet consisting of plants, seeds, fruits, eggs, and lizards. They were between 10 and 13 feet long and 7 feet tall, lived in western North America in the Cretaceous.
