Saurischian Dinosaurs

What were the ornithomimosaurs like in the Cretaceous period?

The ornithomimosaurs, or ostrich-like dinosaurs, were similar to those in the Jurassic period. They had long, flexible necks and a small head; they also had long forelimbs. These dinosaurs had no upper teeth, and their lower teeth were not well developed. Ornithomimosaurs probably reached lengths of up to 20 feet (6 meters).
