Invasion of the GIANT RODENTS

The full magnitude of the world’s largest ever rodent has been revealed- the now-extinct monster was the size of a cow … “Imagine a weird guinea pig, but huge, with a long tail for balancing on its hind legs and continuously growing teeth”.

The first rodents appeared about 40 to 50 million years ago … Rodents are now the most diverse group of mammals with more than 2,000 species; 40% of all mammalian species. “And they also have a huge size range – over ten orders of magnitude. But at a stroke this new fossil stretches this size range by more than another order of magnitude and reshapes our view of the evolution of these animals.”
