Machine-generated Phanerozoic diversity curves.

Genus-level diversity generated by PDD for the whole document set. (a) Total genus diversity calculated as in Fig. 2. For comparison, Sepkoski's genus-level diversity curve [3], [4] is plotted using his stage-level timescale. (b), Diversity partitioned by genera resolved to select classes by PDD. Data for analyses accessible in File S5.
