What are the horns of Rhinos made of?
Additional Information: The Rhino horns are made up of a fibrous protein material called “keratin”. It is a non-mineralized material found on many living mammals, reptiles, birds, and amphibians. The “keratin” that makes up the Rhino horn, is the same material that makes up claws, hooves, nails, and hair. The harder form is usually found in the reptiles, claws, shells, scales, and the birds, beaks, claws, and even feathers. For more details, and examples please see sites listed below.
