摘要： A left upper third molar are found on a skull of fossil giant panda，unearthed near Liuchou, Guangxi. So far as we know, this has not been reported before. As there are three molars on each side of the maxilla in the ancestors of late carnivoral mammals, the occurrence of the upper third molar in this case may be considered as a phenomenon of atavism.
    The strong talon of the left M² on the skull is not present, and the occlusal surface of left M³ is similar with the talon of a normal M² in shape. So we can not exclude the possibility that the M³ represents the talon detached from the M².
