Tyrannosaurus rex was one of the most ferocious predators to ever walk the Earth. With a massive body, sharp teeth, and jaws so powerful they could crush a car, this famous carnivore dominated the forested river valleys in western North America during the late Cretaceous period, 68 million years ago.
The largest T. Rex tooth found is 12 inches (30 cm) long.
They could sprint up to 20 mph (32 kph).
Their length was up to 12 metres (40 feet).

What kills the T. rex?
rex killed by parasite, not combat, scientists say. One of the world’s most famous dinosaurs — Sue the T. rex at the Field Museum in Chicago — died of a parasitic infection, not in a fight with another dinosaur, researchers say.
Then, estimating that the total geographic range of T. rex was about 2.3 million square kilometers, and that the species survived for roughly 2 1/2 million years, they calculated a standing population size of 20,000.
Did T. rex live in England?
Britain was home to some 100 species of dinosaur, including three cousins of the fearsome carnivore Tyrannosaurus rex, according to the author of a new book. Dr Dean Lomax, who is a palaeontologist and Visiting Scientist at The University of Manchester, claims T-rex’s UK cousins were likely smaller and more agile.
What is the oldest dinosaur?
At 243 million years old, Nyasasaurus parringtoni may be the oldest known dinosaur. Sterling Nesbitt, a palaeontologist at the University of Washington in Seattle, and his colleagues describe the animal in a study published today in Biology Letters1.
Did T. rex and humans live at the same time?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
Did T. rex have 3 fingers?
T.rex also had only two fingers on its hands, rather than the three seen in most other carnivorous dinosaurs, so its arms and hands really do appear to have been less important than they were in its relatives.
What’s an interesting fact?
It is physically impossible for pigs to look up into the sky. The “sixth sick sheik’s sixth sheep’s sick” is believed to be the toughest tongue twister in the English language. If you sneeze too hard, you could fracture a rib. Wearing headphones for just an hour could increase the bacteria in your ear by 700 times.
No one has yet positively identified tyrannosaur eggs or hatchlings, but the size of the new embryonic dinosaurs matches with large, elongated eggs that paleontologists have found before. From the size of the embryos, researchers think tyrannosaurs were curled up in eggs that measure about 17 inches long.
Did T. rex lay eggs?
No T. rex eggs or nests have ever been found, but fossils of other Tyrannosaur relatives suggest that they laid elongated eggs, roughly 20 or more at a time. Adult T.
How long is a dinosaur pregnant?
Summary: Researchers have set the timeline it took dinosaurs to incubate at three to six months, depending on the dinosaur. A human typically gives birth after nine months.
How did dinosaurs get pregnant?
Dinosaurs must have had sex to reproduce. As in nearly all modern-day reptiles, males would have deposited sperm inside females, which would later lay fertilized eggs containing developing dinosaur embryos.
Did T. rex have color vision?
Find out why birds of prey have such superior eyesight. And since birds and crocodiles—the closest living relatives of tyrannosaurs—can see ultraviolet light in addition to the colors seen by humans, scientists think it’s likely that T.rex could see an expanded spectrum of color.
Did dinosaurs have 2 Hearts?
There’s no evidence that dinosaurs of any sort had bizarre accessory hearts, but the idea has still played a small role in the ongoing investigation into how giant dinosaurs actually lived. To start, we have to go back to ancient bones and the ways in which paleontologists put them together.
