    It’s amazing how much you can infer from the shape and size of the various features of a bone.

    For eyesight, simple physics: bigger is better. That’s why we build huge telescopes, they collect more light and have better angular resolution than small ones, and the same goes for eyes. In addition, birds in general have very good eyesight and dinos are very closely related to birds. For T. rex, they also have narrow snouts allowing for excellent binocular vision.

    Smell is similar—big nasal cavities allow for big olfactory organs, meaning a lot of receptors that can bind with airborne molecules.

      That really is amazing. But why did we previously think that the T-Rex’s eyesight was terrible, then (as seen in the first Jurassic Park movie)?

        The JP movie (and book, too) took a lot of artistic license. Which is understandable; if the T. rex was depicted as having realistic senses, it would have been a quite short movie with a grizzly ending. And realistic velociraptors wouldn’t have been as intimidating—they’s been small and quite dumb.

        What I really wish is that they’d done the vocalisations of T. rex more realistic—the high pitched screaming was not right. Imagine if the first sign of the rex wasn’t ripples in the water glass but the barely perceptible sub-20 Hz vocalisations from the distance that grow loud and nauseating as it gets close. Granted, not many sound systems could reproduce it—mine can and it’s glorious.

          Just curious, since most postpone can only hear from 20-20k Hz or something and since most sound systems don’t go lower, what kind of media to you listen to that actually go that low? Why would anyone record it if only you and a few other audiophiles can reproduce it?
