base notes	Chron C2n (= Olduvai Normal). "Near LAD of Discoaster brouweri and MIS 71/72 transition.""Site U1308 result implies an age for the base Olduvai, on the LR04 timescale, of 1925 ka"" (review by Channell et al., 2020, of difficulties dating the onset)". Ar-Ar dating agrees with astronomical-cycles (e.g., Channell, 2002).				comp notes
