Distribution of Camels (family Camelidae)

Camelidae: Camels occur in Old World deserts and the Andes region of South America. This southern hemisphere distribution might be thought to suggest a Gondwannan origin. However, the current distribution is a remnant of a nearly cosmopolitan distribution during the Tertiary, and the earliest fossils of camels come from North America, where they have been extinct since the last glaciation.
