What is a Tyrannosaurs Rex?

Tyrannosaurus Rex (T-rex) was a fierce predator that roamed the Earth abetween 70 and 65 million years ago. Tyrannosaurus means “tyrant lizard” in Greek, and “rex” means “king” in Latin. It was so-known as “King of the Tyrant Lizards.” The T. Rex has a massive brain for a dinosaur that would have helped it find its prey. Large portions of its brain enhanced its sight and smell, and it may have possessed telescopic vision.

From its snout to the tip of its formidable tail, this dinosaur’s muscular body reached a length of 40 feet. T-Rex strode through its area on two powerful legs, weighing up to eight tons (16,000 pounds). It also possessed muscular thighs and a powerful tail, which let it move rapidly and counterbalanced its massive head. It was considered exclusively in North America and Asia up until recently. Tyrannosaurus Rex existed in the Late Cretaceous Period, between 70 and 65 million years ago. According to fossil evidence, the Tyrannosaurus Rex lived in what is now Montana and Wyoming. However, at Dinosaur Cove in Victoria, Australia, scientists recently uncovered a hip bone belonging to a T Rex progenitor.

The T-rex did not live very long, even as the king of the jungle. The oldest known fossil was roughly 28 years old and had experienced a lot of trauma during its life. It’s unclear if the T-Rex lived such a short life because of frequent conflict (and died due to its injuries) or because of other factors. According to the study in Science, researchers estimate that 20,000 T-Rex lived at any given period and that the dinosaurs lived and died in around 127,000 generations. Over a two to three million year period, such estimates suggest that 2.5 billion T-Rex roamed North America, maybe as far north as Alaska and as far south as Mexico. What kind of food did the Tyrannosaurus Rex eat? The Tyrannosaurus Rex ate meat from other animals and dinosaurs, but whether it was a predator (hunted and killed its meal) or a scavenger is contention. Many scientists believe the dinosaur was responsible for both. The speed of the dinosaur determines a lot. Some believe the T-Rex was quick and capable of catching its prey. Others claim the dinosaur was slow and used its terrifying jaws to frighten other predators and steal their prey.

Relatives of Tyrannosaurus Rex, according to research published in Science, the closest living relatives of Tyrannosaurus Rex are chickens and ostriches. Paleontologists were able to pinpoint the relationship thanks to material unearthed in an accidental find in 2003. The dinosaur-ness of birds has long been believed based on anatomical similarities, but this is the first molecular proof. The scientists were unable to extract any DNA from the ancient remains. They did, however, recover collagen molecules, a structural protein found in a variety of mammals in somewhat varied configurations. Researchers used people, chimps, mice, chickens, ostriches, alligators, and salmon to compare the dinosaur version with 21 extant animals, including humans, chimps, mice, chickens, ostriches, alligators, and salmon. Collagen from T-Rex will be most comparable to chickens and ostriches, with alligators coming in second.
