Fig. S1. Comparison between actual (‘total’) and sampled diversity curves
Comparison between ‘total’ generic diversity curves for conifers (derived from
Cascales-Minana & Cleal, 2014, and the Paleobiology Database) and the genera
sampled in our study (Hart, 1987).
Comparison between ‘total’ species diversity curves for the pine family (derived from
the Paleobiology Database) and the species sampled in our study (Klymiuk & Stockey,
2012).
Comparison between ‘total’ familial diversity curves for angiosperms (derived from
Cascales-Minana & Cleal, 2014) and the families sampled in our study (Doyle &
Endress, 2014).
Comparison between ‘total’ generic diversity curves for palms (derived from Baker et
al., 2009, Harley, 1996 and the Paleobiology Database) and the subfamilies sampled
in our study (Baker et al., 2009).
Comparison between ‘total’ species diversity curves for water lilies (inferred from the
time-calibrated molecular tree of Yoo et al., 2005) and the species sampled in our
study (Borsch et al., 2008).
Comparison between ‘total’ generic diversity curves for leptosporangiate ferns
(derived from the Paleobiology Database) and the genera sampled in our study (Pryer
et al., 1995).
