Desert-Adapted Crocs Found in Africa

Hillary Mayell, National Geographic News

This National Geographic site details the discovery of several small communities of crocodiles living on the southern edge of Africa's Sahara in desert conditions. The desert crocodiles have apparently adapted to the changing environment in northern Africa; 8,000 to 10,000 years ago, what is now desert was probably lush savannah and grasslands.
