[00:00:00]Did you ever wonder what a T-Rex actually saw when it looked at you?

[00:00:03]Because it wasn't just a blurry blob of screaming human. It was seeing you in full vivid color and in terrifying detail. For decades, scientists assumed dinosaurs saw the world the way most reptiles do, dull, washed out, basically color blind. They were wrong. Dinosaurs evolved from archosaurs, the same ancient lineage that gave us modern birds. And birds have four types of color receptors in their eyes. Humans have three, which means birds and almost certainly many dinosaurs could see colors that literally do not exist in the human experience, like ultraviolet light. Researchers found melanosomes, the tiny structures that create color, preserved inside fossilized [music] feathers. Using that, scientists could reconstruct actual pigmentation. Some dinosaurs had iridescent plumage, like a peacock. So, a velociraptor wasn't just hunting by sound and movement, it was reading color signals in feathers, [music] skin, and probably the environment that you would be completely blind to. T-Rex had forward-facing eyes with a binocular field of view wider than a hawk's. It had depth perception so sharp, it could judge [music] the exact distance of a moving target with surgical precision. It possibly had UV-enhanced sight, too, which means that famous scene where the T-Rex can't see you if you don't move was completely wrong. So, dinosaurs weren't wandering through a gray, blurry world. Most of them had better color vision than you do right now.
