Juvenile Tyrannosaur

The juvinile tyrannosaur was only seen in the novel. It was a 3rd grown and was the same color as the adult. It is seen by Grant in the chopper as they leave Nublar when a bomb explodes possibly killing it. But, it is also possible that it was on Nublar during the film because Nedry is seen stealing tyrannosaur DNA meaning that there are more tyrannosaurs on the island at the time. It was said that it took down a Sauropod, so it may have been stronger than the adult Tyrannosaurus. And it was last seen attacking a Stegosaurus.
