Rhinoceros Evolution Timeline | From Tiny Mammals to Mighty Rhino

A rhino’s horn is made of keratin. The same thing that makes your hair and fingernails. #EarthDay #AWFfacts | African Wildlife Foundation

Did you know a rhino’s horn is made up of the same material as your fingernails? Just as we can cut or file our nails down, rhinos can rub and shape their horns! This helps explain why Doppsee has such a long horn while Phineus has a much shorter horn. We wonder how Jaali will keep his? #rhino #rhinohorn #savetherhino #rhinocalf #savingspecies | Potter Park Zoo
