The unpaired horn of the rhinoceros is obviously very different from other horns. It is a large cone-shaped mass of horn, in the base of which numerous small skin papillae penetrate in their own tubes. These tubes become increasinly narrow going in distal direction, because they are slowly filled with pieces of horns on the sides, and continue through the horn. The horn is attached to the surface of the nose, and does not have a bony nucleus. At most the bone under the basis of the horn is a little bit higher and there is a similar hole in the horn base.
