Huge Rodent Was Bigger than a Bull | LiveScienceThe largest rodent that ever lived weighed a ton or two, scientists revealed today.
The extinct mouse-like critter was larger than a bull.
An amateur paleontologist discovered the exceptionally well-preserved 20-inch-long fossil skull of the gargantuan rodent — dubbed Josephoartigasia monesi — embedded in a boulder on a beach in Uruguay. Scientists estimate this creature lived roughly 4 million years ago in South America, alongside terror birds, saber-toothed cats, giant sloths and massive armored mammals.
J. monesi weighed roughly 2,600 pounds on average, perhaps reaching up to 5,700 pounds.
That is one big mouse! :eek
