Deinonychus (pronounced /daɪˈnɒnikəs/) (Greek δεινος, 'terrible' and ονυξ/ονυχος, 'claw') was a genus of carnivorous dromaeosaurid dinosaur. There is one described species, Deinonychus antirrhopus. This 3.4 metre (11 ft) long dinosaur lived during the early Cretaceous Period (Aptian - Albian stages, 121 to 98.9 million years ago). Fossils have been recovered from the U.S. states of Montana, Wyoming and Oklahoma, though teeth that may belong to Deinonychus have been found much farther east in Maryland. |
