Neat and gross: Eight-foot rodent fossil found in Uruguay

Dios:

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 4 million years ago, when the continent was not connected to North America. A herbivore, the beast may have been a contemporary, and possibly prey, of saber-toothed cats.

For those afraid of rodents, forget hopping on a chair. Its huge skull, more than 20 inches long, suggested a beast more than eight feet long and weighing between 1,700 and 3,000 pounds.
