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.
The horns also make the animals a prized game trophy, which has led to the near-extinction of the two northern species. As an introduced species Between 1969 and 1977, the New Mexico Department of Game and Fish in the US intentionally released 95 gemsbok into its state's White Sands Missile Range [ 14 ] and that population is now estimated ...
Antlers, complex and unique weapons that are an extension of an animal's skull, are found among male deers, as well as female reindeers, ungulates who are even-toed ruminants. [6] Horns , permanent pointed projections consisting of a covering of keratin and other proteins surrounding a core of live bone , are found commonly among bovids , as ...
The other major difference is that antlers undergo an annual cycle of shedding and growth, whereas horns are normally kept for the animal’s entire lifespan (though the pronghorn is an exception ...
Its antlers are strong enough to dig the earth for food like moss and lichen. It also uses its hoofs to break through and shovel through the snow. Little wonder its second name, caribou, means ...
In contrast to antlers, horns—found on pronghorns and bovids, such as sheep, goats, bison and cattle—are two-part structures that usually do not shed.

Most modern pecorans (with the exception of the Moschidae) have one of four types of cranial appendages: horns, antlers, ossicones, or pronghorns. [6] True horns have a bone core that is covered in a permanent sheath of keratin. They are indicative of Bovidae. Horns develop in the periosteum over the frontal bone, and can be curved or straight.
