Snap together the King of Lizards with this ferocious Tyrannosaurus Rex puzzle. Possessing jaws that produced three times more bite force than a lion, these therapods from the Cretaceous period could tear off meat from their prey or chomp limbs, bones and all. Tyrannosaurs hunted with depth perception made possible by forward-facing eyes and counterbalancing tails which allowed them to sprint towards fleeing plant-eaters.
