The Tyrannosaurus rex is one of the biggest and best-known dinosaurs in the genus Tyrannosaurus. This is most likely because it was one of the most dangerous predators ever living on Earth. The T. rex has a big head with eyes that look forward, big jaws with strong teeth that have serrations, a muscular tail, and small arms.
Here are some unique facts about the Tyrannosaurus Rex Fossils-
Diet
The Tyrannosaurus Rex ate meat from living animals, and dinosaurs are no longer alive. It is not known if it was a predator or a scavenger. Many experts think that the dinosaur did both of these things. How fast the dinosaur moves make a big difference. Some say the dinosaur was slow and used its scary teeth to scare off other predators before taking their food.
Size
Based on fossils, scientists think a Tyrannosaurus rex could grow up to 40 feet long and 12 feet tall. T. rex is thought to have weighed between 11,000 and 15,500 pounds. It had skin and flesh on tyrannosaurus bones. About that much is how much the most prominent African elephant weighs.
Teeth
The longest tooth found on a meat-eating dinosaur was 12 inches (30 cm) long and in T. rex's mouth. Still, a study published in 2012 in the Canadian Journal of Earth Sciences found that not all dinosaur teeth were used similarly. The dinosaur's front teeth, in particular, grabbed and pulled. Its side teeth tore tissue, and its back teeth cut meat and pushed it down the throat.
Age and Extinction
The average life span of a Tyrannosaurus rex was about 28 years. Researchers had found that it had a growth spurt when it was a teenager, but until recently, they didn't know much about how it went from being a tiny hatchling to a powerful predator.
Key Takeaway-
No fossil of a T. rex has ever been found, so no one knows how many tyrannosaurus bones there are. It probably had 200 bones, which is about the same as ours. In the late Cretaceous period, 68 million years ago, this well-known animal ruled the wooded river valleys of western North America.
