As Zeus was to the Greeks, This gravitational lens was discovered by Dennis Walsh. Brontosaurus also consumed stones to help grind up and digest unchewed plant matter once it reached the stomach. So far, the best specimen shows that the particular T. rex who made the tracks was moving at about 10 miles per hour. This is NPR News. Scientists who do not agree say that not enough specimens have been collected to truly recognize robust and gracile morphotypes or any significant differences in the skeletons, and we probably never will know the answer. The study, published in Friday's issue of the journal Science, assessed 21 species of dinosaurs, including the predators Tyrannosaurus and Allosaurus, the long-necked Apatosaurus, the duck-billed Tenontosaurus and the birdlike Troodon as well as a range of mammals, birds, bony fish, sharks, lizards, snakes and crocodiles. One feature of Tyrannosaurus rex that everyone makes fun of is its arms, which seem disproportionately tiny compared to the rest of its massive body.

In 2006, Kent Stevens from the University of Oregon did an experiment inspired by that very scene to figure out what sort of binocular range (the field of view both eyes can see simultaneously) T. rex might have had. It turns out that T. rex had pretty amazing visionbetter than people and even hawks have. Even if that T. rex was blind, he would have smelled that boy, not to mention being able to identify what he'd had for dinner an hour earlier.

Single T. rex tracks have been found, but trackways with more than one step are rare. Did T. rex have color vision? In T. rex, it would have resulted in excellent dinosaur athletes who would have no trouble running the Boston Marathon! While Velociraptor would have beaten T. rex in a game of chess - because its cerebrum, the brain's "thinking" part, was relatively larger - T. rex still was no dummy. This would have included plenty of space for black-and-white and color receptors; since its ancestors (crocs) and its descendants (birds) see in color, scientists think T. rex did, too. Stevens was able to determine that T. Rexs binocular range was 55 degrees, which is greater than a hawk, which is known for its high visual acuity. WebDid T. rex have color vision? They were a reddish-brown color. The creatures have been extinct for 65 million years, but scientists evaluated the metabolism of numerous dinosaurs using a formula based on their body mass, as revealed by the bulk of their thigh bones.

The eyes of T. rex face forward, giving them stereoscopic vision for seeking prey. Although not as intelligent as most modern birds, or animals. T. rex had a wide field of binocular vision around 55 degrees. And it would have only gotten better. Allosauroids, including Carcharodontosaurus[1] and Allosaurus, did not have very good binocular vision, comparable to modern crocodiles. Scientists measure the stride length (the distance from one step to the next for the same foot) and then divide that distance by the length of time it took to make the stride.

Tyrannosaurus rex has long been depicted with scaly, reptile-like skin. The Brontosaurus was a herbivore. Warmblooded animals need to eat a lot, so they are frequently hunting or munching on plants. T. rex had a bite force of 7,800 pounds, equivalent to the crushing weight of about three Mini Cooper cars. Most hatchlings didn't survive past infancy. The wider that range, the better an animals depth perception and capacity to distinguish objects that are motionless or camouflaged. So far, it's small-ish creatures who wore feather coats, and it's very probable that T. rex also had feathers.

In The Lost World: Jurassic Park it was revealed that male Tyrannosaurus rex have green colored skin. But what colors? It is revealed that Blue is still alive, but she and many other creatures will now face an impending danger, in the form of an erupting volcano. The binocular vision of Daspletosaurus has been found to be less than that of Stenonychosaurus, but more than that of Gorgosaurus. Vinther and scientists from Virginia Tech confirmed traces of melanin in fossils dating back millions of years, and that melanin may provide a vital clue.
