This site describes the Ornithomimids, a distinctive group of theropod dinosaurs who show a good example of convergent evolution with the ratite birds, such as ostriches. They were not as closely related to birds as the Dromaeosauridae were, but were still members of the well supported group Coelurosauria, which includes birds. The site describes their classification, morphology, locomotion, and eating habits. This site also includes active links for further study.
