T. Rex's vision would allow objects up to six kilometers away to remain in focus, a distance that equates to 1.6 kilometers for humans. “With the size of its eyeballs,” Stevens said, the T. Rex “couldn't help but have excellent vision.”

Reptiles, such as crocodiles and lizards, have legs that sprawl out to the side. Their thigh bones are almost parallel to the ground. They walk and run with a side-to-side motion. Dinosaurs, on the other hand, stand with their legs positioned directly under their bodies.

Nocturnal animals possess a pathway through which rods connect to the same “dark” circuits used by cones, which allows them better perception of edges, movement, and silhouettes in dim light. Even the nuclei of the rod cells are adapted for night vision.

The Laetoli footprints provide a clear snapshot of an early hominin bipedal gait that probably involved a limb posture that was slightly but significantly different from our own, and these data support the hypothesis that important evolutionary changes to hominin bipedalism occurred within the past 3.66 Myr.

They use sunglasses/dim glasses for protection. Since they are known for having the characteristics of insects, we can assume that they have crepuscular vision and some have nocturnal traits - meaning that they are most active in twilight/low light/night. Their eyes are highly adapted on low light.

The Tyrannous Rex not only could see just fine, whether the object was moving or non-moving (which helps one not run into things), there's also quite a bit of evidence that the T-Rex's sight was extremely good, very possibly better than modern-day hawks and eagles.

The precise purpose of T. rex's relatively tiny arms has long been mysterious. Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex.

Tyrannosaurus rex lived in forested river valleys in North America during the late Cretaceous period. It became extinct about 65 million years ago in the Cretaceous-Tertiary mass extinction.

Bigger Than T. Rex: Spinosaurus. The water-loving Spinosaurus had a spiny “sail” on its back, and a crocodile-like head, neck and tail, but was much larger than the Tyrannosaurus Rex. At 50 feet long, it's the largest carnivore to walk (and swim) the Earth… that we know of.

rex arms were used to slash prey in close proximity to the dinosaur. The arms, which were approximately three feet long, featured crescent-shaped talons that could be used to inflict mortal wounds to prey. And the short arm length was actually more beneficial for slashing, considering the size of T. rex's head.

The Tyrannosaurus Rex was not a lone operator as previously thought but hunted in packs, new research has found. Tyrannosaurids, including the Tyrannosaurus Rex, have traditionally been portrayed by experts as formidable but solitary and dull-witted creatures because their skeletons were found alone.

Researchers on Wednesday said a computer model based on the T. rex jaw muscle anatomy and analyses of living relatives like crocodilians and birds showed its bite force measured about 8,000 pounds (3,630 kg), the strongest of any dinosaur ever estimated. “T.

T. Rex Linked to Chickens, Ostriches. The closest living relatives of Tyrannosaurus rex are birds such as chickens and ostriches, according to research published today in Science (and promptly reported in the New York Times).

In popular culture The "raptors" portrayed in Jurassic Park were actually modeled after the closely related dromaeosaurid Deinonychus. Paleontologists in both the novel and film excavate a skeleton in Montana, far from the central Asian range of Velociraptor but characteristic of the Deinonychus range.

The theropod (meaning "beast-footed") dinosaurs are a diverse group of bipedal saurischian dinosaurs. ... What most people think of as theropods (e.g., T. rex, Deinonychus) are extinct today, but recent studies have conclusively shown that birds are actually the descendants of small nonflying theropods.
