Today you get two images from the Paleontology section of Museo di Storia Naturale (Natural History Museum), Universitá degli Studi di Firenze in Florence, Italy — first, the skull of an Arsinoitherium Zitteli:
Next, a nice sketch of what these critters looked like in life:
Arsinoitherium was somewhat like a rhinoceros, only better (from the standpoint of armaments) — with two big horns, plus little horns over the ears. They lived in what’s now northern Africa from about 36 million to 30 million years ago. Oddly enough, its limb bones suggest this critter was more closely related to modern-day elephants than to rhinos.
