Similarity of the Cerrejón megaflora to living Neotropical forests. Histograms are the frequency distributions of Spearman rank order correlation coefficients derived from all pairwise comparisons of 72 living forest sites [SI Appendix (see Table S5)]. Arrows show the mean similarity of the Cerrejón flora to all living sites (red, conservative identifications of fossils; green, best-guess identifications). Black lines represent 95% confidence intervals. See SI Appendix (Table S5) for additional information.
