Extended Data Fig. 10: Estimated origination times across angiosperm families.

a, Posterior samples of the oldest time of origin across all families obtained after combining the estimated ages of each. The red line indicates the boundary between the Jurassic and the Cretaceous. Only 0.2% of the samples fall within the Cretaceous providing strong statistical evidence for an earlier origin of crown angiosperm. b, Root age estimates of extant families of angiosperm with 95% credible intervals (left) as inferred from meso- and macrofossils only, excluding pollen data and cumulative family diversity (right) based on those estimates (Y-axis is log10 transformed). The analyses we run under a BBB model with time-increasing sampling rates. c, Root age estimates of extant families of angiosperm with 95% credible intervals (left) as inferred from a BBB model with sampling rate set to be constant (parameter a = 0) and cumulative family diversity (right) based on those estimates (Y-axis is log₁₀-transformed).
