Giant prehistoric rat the size of a human roamed Earth 10 million years ago

It’s not something you’d want to see scurrying away in your kitchen – a rat the size of a human being, weighing almost 13 stone. 

The vast rodent roamed the Earth 10 million years ago, scientists say, living in the Amazon rainforest. 

It was also extremely stupid, scientists believe.

The monstrous rat has been named Neoepiblema acreensis after the skulls of two individuals were found at a fossil site at Acre in the western Brazilian Amazon.
