The primary difference between antlers and horns is that the former are seasonal while the latter are permanent. Antlers are the fastest-growing tissue on the planet, expanding at a rate of up to ...
Similar to species with horns or antlers, male giraffes use their ossicones as weapons during combat, where they use their heads as clubs: the ossicones add weight and concentrate the force of impact onto a small area, allowing it to deliver heavier blows with higher contact pressure. [4]
Rhinoceros horns, unlike those of other horned mammals, consist only of keratin. These horns rest on the nasal ridge of the animal's skull. Antlers are unique to cervids and found mostly on males: the only cervid females with antlers are caribou and reindeer, whose antlers are normally smaller than males
True horns are found mainly among: Ruminant artiodactyls. Antilocapridae ; Bovidae (cattle, goats, antelopes etc.). Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones. Cervidae: Most deer have antlers, which are not true horns due to lacking a bone core and made of keratin.

Horns develop in the periosteum over the frontal bone, and can be curved or straight.

[4] Antlers are bony structures that are shed and replaced each year in members of the family Cervidae.
