A nannofossil zonation chart

The chart below, from TimeScaleCreator, provides a compilation of nannofossil zonations from throughout the geological range of coccolithophores. It is a big chart but it seems to work fine with modern browsers and it provides a graphic indication of the duration of geological time over which nannofossils occur. All Ma ages on the Nannotax website are currently based on this timescale (GTS2012).
