Mighty Mouse

Oh, I can imagine this:

Imagine a rodent that weighed a ton and was as big as a bull.
Uruguayan scientists say they have uncovered fossil evidence of the biggest species of rodent ever found, one that scurried across wooded areas of South America about four million years ago, when the continent was not connected to North America.
