In 1898, two male lions terrorized an encampment of bridge builders on the Tsavo River in Kenya. The lions, which were massive and maneless, crept into the camp at night, raided the tents and dragged off their victims. In a new study, Field Museum researchers collaborated with scientists at the University of Illinois Urbana-Champaign, inlcuding Illinois Anthropology faculty Ripan S. Malhi, on an in-depth analysis of hairs carefully extracted from the lions’ broken teeth. The study used microscopy and genomics to identify some of the species the lions consumed. The findings are reported in the journal Current Biology. Read about the collaboration here.
