Figure 12. Diatom diversity vs carbon cycle proxy mean global benthic ∂¹³C.

a) Three point moving average of three diatom diversity time series estimates from figure 7 (blue line) vs time series of ∂¹³C [22] (red line). Diatom diversity vs ∂¹³C over the Cenozoic. Symbols as in figure 11. Age scale: [43].
