Fossil hunters have uncovered the greatest rodent that ever lived -- a one-tonne behemoth that bestrode the swamplands of South America some four million years ago. The skull of the extraordinary beast which measures a whopping 53 centimetres (21 inches) was found in a broken boulder on Kiyu Beach on the coast of Uruguay's River Plate region. Despite its fearsome look, the creature was not carnivorous and looked more hippo-like than rat-like. The newly-found species has been dubbed Josephoartigasia monesi. http://afp.google.com/article/ALeqM5gkiqtoPA5N7uxC_140qV3fzwnv9Q.
