The Nevada Museum of Art has not one--but two--horse exhibitions on display right now. The first is called, well, The Horse and it's a traveling show that shares the history of horses, which were actually pretty different 50 million years ago.
"Some of them were the size of small dogs all the way up to the size of present day horses," says JoAnne Northrup with the museum. "There was a huge range of forms, too. Some of them looked a little bit more like zebras. It's just crazy."
