Figure 7. — Median indices of stratigraphic congruence (GER, GERt, GER*, SCI, and MSM*) vary significantly across geological periods, while their residuals (from minimum adequate models) do not. Trees are binned according to the mean date of FO of their constituent taxa. Median values are indicated by black horizontal bars, shaded areas represent upper and lower quartiles, and dashed lines connect to the most eccentric points within 1.5 interquartile ranges of the medians. Outliers are shown as circles. All polytomies treated as hard (resolved in reverse stratigraphic order). Abbreviations: Ca, Cambrian; O, Ordovician; S, Silurian; D, Devonian; C, Carboniferous; P, Permian; Tr, Triassic; J, Jurassic; K, Cretaceous; Pg, Paleogene; Ng, Neogene.
