英文摘要	The age when the giant panda (Ailuropoda melanoleuca) transitioned to a bamboo dominant diet has not been well established due to the lack of fossil evidence. In particular, a radial sesamoid bone, which acts as a 'pseudo-thumb', has been used as evidence of giant pandas' adaptive evolution to bamboo specialised consumption, but no relevant fossil evidence has been reported thus far. Shuanghe Cave is the longest cave in Asia, and produced fossils of more than 20 giant pandas, including relatively intact fossil skeletons of two adult giant pandas. The uranium-series dating of the fossilised teeth of the two giant pandas indicates ages earlier than 102 ka and 49 ka. Tooth wear for both individuals is not apparent, indicating that they were young at the time of death. From the skeletal fossils, for the first time, a 'pseudo-thumb' fossil of a giant panda was discovered. Our morphological comparison indicated that as early as 100,000 years ago, giant pandas had evolved an enlarged radial sesamoid bone (pseudo-thumb) that is comparable to that of the modern pandas, suggesting that in the early Late Pleistocene at the latest, giant pandas possessed physical conditions allowing them to dexterously grab bamboo with their manuss.
