A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone.

Horns are distinct from antlers, which are not permanent. Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Partial or deformed horns in livestock are called scurs. Giraffidae: Giraffes have one or more pairs of bony bumps on their heads, called ossicones. These are covered with furred skin. Cervidae: Most deer have antlers, which are not true horns and made of bone.

Rhinocerotidae: The “horns” of rhinoceroses are made of keratin, the same substance as fingernails, and grow continuously, but do not have a bone core. Chamaeleonidae: Many chameleons, most notably the Jackson’s chameleon, possess horns on their skulls, and have a keratin covering. Ceratopsidae: The “horns” of the Triceratops were extensions of its skull bones, although debate exists over whether they had a keratin covering. Abelisauridae: Various abelisaurid theropods, such as Carnotaurus and Majungasaurus possessed extensions of the frontal bone which were likely covered in some form of keratinous integument.

These lizards have horns on their heads which have a hard keratin covering over a bony core, like mammalian horns. These are pointed outgrowths of the hard chitinous exoskeleton. Canidae: Golden jackals are known to occasionally develop a horny growth on the skull, which is associated with magical powers in south-eastern Asia. Azendohsauridae: the skull of the triassic azendohsaurid archosauromorph Shringasaurus possessed two massive, forward-facing conical horns, which were likely covered in cornified sheaths in life.
