A very small (about a meter long) <i>bixi</i> turtle In the Ming-era section of  the Confucius Cemetery, somewhere NW of the tomb of Confucius. Rather unusually, instead of a rectangular niche on for a tablet, this <i>bixi</i> appears to have on its back a round niche (for a round pillar?). <br> 
While I can't date the <i>bixi</i> itself, one nearby tombstone (not necessarily related to the <i>bixi</i>) belongs to a 61st-generation descendant of Confucius, and is dated 36 Wanli (ca. 1608); another, Hongzi 17 (ca. 1504). Yet another tablet, to the south-east of this bixi, has the inventory number 9-223 written on it.
