16 January 2008 – Skull of a 1,000 kg rodent discovered


Palaeontologists in Uruguay have discovered the skull of a rodent that weighed an estimated 1,000 kilograms, based on the skull’s measurements and a comparison with the remains of other rodents. The newly discovered species, Josephoartigasia monesi, would have weighed twice as much as the largest known rodent until now, Phoberomys, and 16 times more than the capybara (also known as the carpincho or “water hog”), which at 60 kilograms is the largest living rodent in the world.
