‘What’ a savage old dino

A TERRIFYING predator that lived 340 million years ago has been dubbed “the T Rex of its day”.

Named Whatcheeria, it had razor-sharp teeth and bone-crushing jaws that snapped animals in half.

The tetrapod was one of the first creatures to hunt on land – and topped the food chain, a new study has found.

It had a salamander-like body and long narrow head, reaching more than six feet from nose to tail.

Ben Otoo, from the University of Chicago, said: “If it really curled up, probably to an uncomfortable extent, it could fit in your bathtub, but neither you nor it would want it to be there.”
