The chart was first produced and web-published on this site. It intended to provide a simple pictorial guide to correlation of the chronostratigraphical subdivisions of geological time during the late Cenozoic, to fulfill Task C of the SQS Science Plan. The chart was compiled by P.L. Gibbard, S. Boreham, K.M. Cohen & A. Moscariello.

The printing and distribution of a poster version was supported by Royal Dutch Shell BV. These privately published hard copies ( v. 2004 ) of the chart contained a serious error: the depicted Vostok curve is not the data of Petit et al. 1999, but in fact a benthic foram deep sea marine curve. Version v. 2004b has this corrected.
