This small dinosaur was discovered in northeastern Arizona’s Kayenta Formation in 2010. Its name translates to “Kayenta hunter.” Kayentavenator was present in North America during the Early Jurassic Period, roughly 145 million years ago.
Kayentavenator dinosaurs were small and only stood about 1.6 feet high. They were carnivores, so they used their small stature to their advantage when hunting prey. The Kayentavenator had long back legs with sharp claws and smaller arms. Paleontologists believe that the Kayentavenator thrived in a river environment with a pleasant seasonal climate. They shared their space with theropods, bony fish, salamanders, frogs, and other reptiles.
