6. (Thomas Lawton, 1978) Attribution changed from Chou [Zhou] 周 to Neolithic.
7. (Julia K. Murray, 1982) "3rd millennium BCE?" is added to the date. Since most of this bangle consists of altered stone, and there is only a small slice of green material on the inside of the ring, it seems likely (in view of the unusually large hole diameter) that some other object was fashioned from the material enclosed by the present ring, and what we have may be the leftover "skin." For a discussion of bangles, see Folder Sheet F1917.387.
8. (Jeffrey Smith per Keith Wilson, May 10, 2016) Period changed from Neolithic to Late Neolithic, with object date changed from ca. 3000-2000 BCE to ca. 3000-1700 BCE.
