The binocular vision of deinonychosaurs, such as Velociraptor and Stenonychosaurus was better than that of allosauroids and it matched or exceeded that of extant predatory birds. It may have used its long neck to reach out of the way food as well as to keep its head away from shorter predators. Because large modern-day warm-blooded animals, such as elephants and rhinoceroses, tend to be dully colored, many scientists think that dinosaurs were, too. AMUN-RA: The Hidden One.
