Meet the Indricotherium, largest land mammal to walk the Earth

 In this photoshopped pic we see a human, an image of the indricotherium, and an African elephant.  Check this link, for source of the photo.  

I'm reading The First Fossil Hunters by Adrienne Mayor right now, which looks at the reports of, and thoughts about ancient fossils by the ancient Greeks and Romans.  She mentioned the Indricotherium as the largest land mammal that ever lived, so I had to look it up.  These ginormous creatures ate plants, weighed 15-20 tons, and lived in East Asia.  They roamed 33 million to 23 million years ago.  More info on this animal and it's cousins on Wikipedia, here.
