Ancient pandas weren`t exclusive bamboo eaters, bone evidence suggests
(PHYSorg.com Archaeology & Fossils)

The giant pandas we know and love today live only in the understory of particular mountains in southwestern China, where they subsist on bamboo alone. In support of their tough and fibrous bamboo diet, they`ve got distinctive teeth, skull, and muscle characteristics along with a special pseudo-thumb, the better to grasp and hold bamboo stems, leaves, and shoots with. But according to new evidence reported in Current Biology on January 31, extinct and ancient panda species most likely had a more varied and complex diet.
