The Mighty T-Rex
One of the biggest and most powerful of all dinosaurs was the world-famous Tyrannosaurus Rex. You may remember it had a starring role in the ‘Jurassic Park’ movies.
But it wasn’t from the Jurassic period, but from the Cretaceous period (85 – 65 million years ago).
Better known to us as T-Rex, it was a very fierce carnivore and scientists believe they could eat up to 500 pounds (230 kilograms) of meat in one single bite. It would crush and chomp down bones, horns and flesh as it ate.
Fossils found by scientists suggest T-Rex was about 40 feet (12 meters) long and about 15 to 20 feet (4.6 to 6 meters) tall. It had strong thighs and a powerful tail that ensured it could move fast. It could use its massive 5-foot-long (1.5-meter-long) skull to head-butt other dinosaurs hard enough to stun them.
T-Rex had large, serrated teeth to pierce and grip flesh, which it ripped off of its prey’s body using its strong neck muscles.
But the strangest thing about T-Rex is that, for a dinosaur so big and powerful, it had tiny two-fingered forearms that don’t appear to have been very useful for much at all!
