This dinosaur used its 60 serrated teeth , each about eight inches long, to pierce and grip flesh, throwing prey into the air and swallowing it whole. To keep itself from overheating while crushing prey with its mighty jaws, the giant animal had vents in its head to help its brain stay cool, similar to those found in alligators. Tyrannosaurus rex was also adept at finding its prey thanks to a keen sense of smell.
While scientists have known for a while that this dinosaur devoted large portions of its brain to processing smell, studies have recently revealed that T. This powerful snout also likely helped T.

Others argue that T. And while they had strong thighs, these dinosaurs were not speedy. They could only walk briskly at up to 12 miles an hour —likely not fast enough to chase a speeding Jeep, as depicted in the movie Jurassic Park. Using biomechanical models, scientists have theorized that if these heavy animals moved any faster, they would have shattered the bones in their feet.
Tyrannosaurus rex had a life expectancy of about 28 years. In January , a study of the fossils of Nanotyrannus —a smaller tyrannosaur that was believed to have lived alongside T. In spite of all its advantages, T. There is fossil evidence that can prove T Rex hunts herbivorous dinosaurs despite its height inferiority. The Allosaurus, a carnivore that stands at 17 feet tall and is known as a top predator of the Jurassic, is taller than a T Rex.
It has serrated teeth that surely do not fail to feast on its prey meat. The famous Spinosaurus can reach up to 14 to 20 feet in height, including its impressive spikes on the back close to the T Rex height range. The body size rivaled the T rex and other carnivores.

There are almost 60 T Rex specimens recovered around the globe, mostly in North America. This 60 includes fragments of bones and a T Rex skeleton that is preserved almost completely. This valuable discovery made it possible for scientists to reconstruct T Rex accurately and closely estimate its actual height. The size estimate of Scotty was based on an estimation technique for mass that utilizes femur circumference. From this data, the mass or body weight can then be calculated.
T Rex height can play both an advantage and disadvantage. The primary benefit of the T Rex height is that it can intimidate smaller predatory dinosaurs. The T rex height is not specialized for reaching high areas for grazing like trees but is suitable for its carnivorous habit. T Rex tops other carnivores too because of its large sharp teeth.
