Deinonychus is a genus of carnivorous dromaeosaurid coelurosaurian theropod dinosaur with one described species, Deinonychus antirrhopus. This species, which could grow up to 3.4 meters (11 ft) long, lived during the early Cretaceous Period, about 115–108 million years ago (from the mid-Aptian to early Albian stages). Fossils have been recovered from the U.S. states of Montana, Utah, Wyoming, and Oklahoma. Now you can print it out and use different colors to create a beautiful picture. Or color online on our site.
