A lone Deinonychus antirrhopus scouts for prey deep in the jungles of Early Cretaceous North America, circa 110 million years ago. Deinonychus was a larger cousin of Velociraptor that was actually even more influential on the design and portrayal of the Jurassic Park “raptors”. Since Deinonychus fossils have been found in groups together with the much larger herbivore Tenontosaurus, some paleontologists have proposed that Deinonychus could have hunted bigger prey in packs (or at least uncoordinated mobs).
