Fig. S1: Crown angiosperm age trace

Figure S1: Traces of the age of the crown angiosperm node across replicate analyses (burnin phase only) for Beaulieu et al. (2015) (top) and Magallo ́n et al. (2015) (bottom) data sets. Top: prior (lognormal priors), orange (n = 2); posterior (lognormal priors), blue (n = 3); prior (exponential priors), red (n = 2); posterior (exponential priors), green (n = 3). Bottom: prior (no angiosperm constraint), orange (n = 4); posterior (no angiosperm constraint), blue (n = 4); prior (all constraints), green (n = 4); posterior (all constraints), red (n = 3; note that this is mostly obscured by the green prior trace). All analyses were initialized with the age of crown angiosperms set at ∼140 Ma.
