While the illustrated and skeletal animals are extinct, all of these creatures are real. So, there you go, depending on your definition of “unicorn,” these monoceroses really weren’t mythical.
Read about them in more detail below the cut, plus sources.

1. Many goats like this were created by removing their horn buds, merging them together, and putting the resulting bud in the middle of their head. They toured with Ringling Brothers. (via SideShowWorld.com)

3. Bull with Fused Horn: In 1933 Dr. D. W. Dove of Maine University took the horn buds from a calf, fused them together, and implanted them back in the calf’s head. When the new, fused horn grew it made the bull look like a unicorn. It looks like he had more concern for making a cool-looking creature than the well-being of a living animal, though. While the initial surgery was a careless experiment, luckily the bull grew up healthy, and even became the leader of the herd. When he challenged other bulls, the unicorn’s centered horn gave him an advantage. Feeling unthreatened, he even became more gentle and docile. (via Unicorn Garden)
4. Elasmotherium: An extinct species of rhinoceros. Maybe they lived long enough to influence unicorn mythology. (via Walter Meyers)
5. Various Extinct Ungulates: This artist has created reconstructions of a small sampling of prehistoric hooved animals. Bramatherium and Prollbytherium are relatives of the giraffe, Candiacervus is a deer, and Hayoceros and Kyptoceras are relatives of the pronghorn antelope. With all this diversity in headgear, it isn’t hard to imagine that at one point there must have been something resembling a unicorn. (via Chinkajin on Deviantart)
6. Tsaidamotherium: An extinct antelope with two horns, but one much bigger than the other. (via Frontiers of Zoology)
7. Kubanochoerus is an extinct pig relative with a bony forehead protrusion. (via Dinogami)
8. Cutaneous horn in human: Wang, a Chinese farmer, had this conical skin tumor growing out the back of his head. (via The Human Marvels)
9. Saola, Pseudoryx, or Asian Unicorn: Many antelope are similar to unicorns, and could have potentially inspired the myth. (via WWF, AFP/Getty Images)
10. Procamptoceros: Had two horns, but they were so close that they were covered in the same sheath. (via Tim Morris)
