T-rex was one of the largest carnivorous dinosaurs to ever live. Evidence took from the fossilized feces of T-Rex suggested it even ate fairly large dinosaurs like Edmontosaurus and Triceratops. T-Rex fossils are found in western North America. The Hell Creek Formation in northern Montana is an area that is world-famous for its fossil dinosaur sites.
Some experts say it’s possible that T-Rex were descendants of ancestral tyrannosaurs from Asia. The first tyrannosaurs, which were human to horse-size, originated about 170 million years ago. The study suggests that the advanced brains tyrannosaurs developed while they were still small helped them become apex predators once they grew to T-Rex’s size about 70 million years ago.
A T-Rex would have been capable of biting down with a force of 35,000 to 57,000 Newtons with its back teeth, which is roughly equivalent to the force of a medium-size elephant sitting down, a stronger bite than any other large meat-eating Dinosaur. T-rex had a mouth full of serrated teeth. They could be over 9 inches long and were very thick, curbed backwards which made them ideal for holding onto struggling live prey.
Its eyes were positioned at the front of its head with its snout dropping down in front of them. This would have given it stereoscopic vision allows them to judge long distances. Its eyes were larger than any other land animal.
Its sense of smell could track its victims from miles away. Its sense of hearing could allow it to detect lower noises in the ground. T-Rex had strong thighs and a powerful tail, which counterbalanced its large head and allowed it to move quickly. The recent study suggests it could run 17 to 40 km/h.
T-Rex was, by Dinosaur standards, a very intelligent animal. Its brain was over twice the size of Spinosaurus or Giganotosaurus. (Floro Mercene)
