Dinosaur vision was, in general, better than the vision of most other reptiles, although vision varied between dinosaur species. Coelurosaurs, for example, had good stereoscopic or binocular vision, whereas large carnosaurs had poor binocular vision, comparable to that of modern alligators.
Most carnosaurs, including Carcharodontosaurus and Allosaurus, did not have very good binocular vision, comparable to modern alligators. They possessed binocular vision which was restricted to a region only 20° wide, which is understandable, as they hunted mostly large and slow prey. Their keenest sense was probably smell.
The eye position of Tyrannosaurus rex was similar to that of modern humans, but their eyes and optic lobe were much larger than that of modern humans. T. rex, unlike most dinosaurs, had a combination of powerful eyesight and great sense of smell.
