Top 6 extinct mammals with the craziest headgear

Just when you thought modern ruminants like the kudu, ibex, and blackbuck had crazy horns, a trip back in time to look at the extinct mammals with the craziest headgear might change your perspective.

Below is an assortment of six extinct mammals with the craziest headgear. It includes mostly animals with horns and only one animal with antlers. Horns are generally bony outgrowths with a live bone core that often are surrounded by keratin coverings. The pronghorn antelope is one such example. Unlike the antelope, the horn of a rhinoceros is mostly made of keratin and sits atop a bony dome. Antlers, on the other hand, are the most fanciful of headgear. They are true bony outgrowths attached to a small bony stump and are generally shed and regrown annually. Males use them to attract females.
