I don't know if "many" have been described thusly, but I do knoow that at
least _Tyrannosaurus_ and possibly _Troodon_ had a narrower range of vision,
as is the case with most terrestrial mammalian predators. It's okay to
sacrifice some of your visual range for stereoscopic vision if you're a
predator. It's generally not the best thing for herbivores because they
need to see more at once and depth perception is not that big of a deal. If
there is a lion or a tyrannosaur, you want to panic!
