Was T. rex
the king?
Tyrannosaurus rex was one of the largest meat-eating dinosaurs
(carnivores) that ever lived. Its name means ‘tyrant lizard king’. T. rex is
seen by many as the king of the dinosaurs.
From bones found in the ground (fossils), we know that T. rex was about
12 metres long and about 4.6 to 6 metres tall. It walked on two large,
strong back legs. It had a huge head, strong jaws and teeth that could
bite through bone. Its mouth was big enough to fit a whole person!
Tyrannosaurus’ arms were small but powerful. With its strong legs and
long, powerful tail, it could move quickly.
For a long time, T. rex was the biggest meat-eating dinosaur that had
been discovered. Then bones of the slightly taller Giganotosaurus
were found. Its skull was big, like T. rex’s, but not as wide or heavy. Its
teeth were shaped more for cutting and slicing than crushing bones.
Giganotosaurus also had a much smaller brain that was the size and
shape of a banana.

Bigger again was Spinosaurus. It may be the largest carnivore to have
roamed the Earth. Although it was bigger, Spinosaurus was lighter than
both T. rex and Giganotosaurus. Its teeth and jaws were big, but not as
strong, and it might have eaten mostly fish.
T. rex wasn’t the largest carnivore, but with its strong teeth, jaws and
legs it was a fierce predator. Many people think it deserves its name.
