Tyrannosaurus means tyrant lizard and “rex” means King.

But there’s a debate going on between palaeontologists; those who study fossil remains from the past.

Perhaps the “King” wasn’t that strong after all? Why not? Some say its teeth were too big, its front legs too short and it was overweight; T. rex was… clumsy…

… and could only eat dead animals or those that couldn’t move.
