A giant lion with enormous fangs that roamed the Kenyan savannah more than 20 million years ago was one of the largest ever meat-eating mammals, researchers said Thursday.

A team unearthed the lower jaw, teeth and other bones of a new species, Simbakubwa kutokaafrika -- Swahili for "big African lion".
