Description
Sivatherium (Shiva's beast) is an extinct genus of giraffid that ranged throughout Africa to the Indian Subcontinent. The African species, S. maurusium, was once placed within the genus Libytherium. It may have become extinct as recently as 8,000 years ago, as depictions that greatly resemble it are known from ancient rock paintings in the Sahara desert. Sivatherium resembled the modern okapi, but was far larger, and more heavily built, being about 7 feet tall at the shoulder. It had a wide, antler-like pair of ossicones on its head, and a second pair of ossicones above its eyes. Its shoulders were very powerful to support the neck muscles required to lift the heavy skull. This animal appeared during Cenozoic era, the most recent era of geologic time, from about 65 million years ago to the present. The Cenozoic Era is characterized by the formation of modern continents and the diversification of mammals and plants. Grasses also evolved during the Cenozoic. The climate was warm and tropical toward the beginning of the era and cooled significantly in the second half, leading to several ice ages. Humans first appeared near the end of this era.
