Now that is a rat.
From the New Scientist story:
A 1-tonne rodent has been discovered by scientists in Uruguay. But there is no need to worry, Josephoartigasia monesi is around 2 million years old and fossilized.
By comparing the skull’s dimensions to the body sizes of existing rodents, the researchers determined that its owner probably weighed about 1000 kilograms, making it the world’s largest known rodent.
Bigger, even, than Walt Disney.
We’re not sure these guys exist either.
