japenese pots are now supposed to be 500 years younger not 5000.
Upper Paleolithic: Yuchanyan Cave
The oldest pottery in the world is from Hunan Province, in China, at the karst cave of Yuchanyan. In sediments dated between 15,430 and 18,300 calendar years before the present (cal BP) were found sherds from at least two pots. One was partially constructed, and it was a wide mouthed jar with a pointed bottom that looks very much like the Incipient Jomon pot illustrated in the photograph and about 5,000 years younger. The Yuchanyan sherds are thick (up to 2 cm) and coarsely pasted, and decorated with cord-marks on the interior and exterior walls.
