base notes	Calabrian (former base of PLEISTOCENE pre-2009) -- The Calabrian begins with "base of a claystone unit conformably overlying sapropel marker bed "e" in the Vrica section of Calabria in southern Italy = MIS 64/65 transition in oceans. This is at or near the top of the Olduvai (C2n) Normal polarity chron. An age of 1.806 Ma for mid-point of underlying sapropel was previously used for the GSSP age also; but Cita et al (2012; Episodes for re-ratification) noted the offset, therefore recommended a 1.80 age.				comp notes
