Figure 6

Timetree derived from the Bayesian relaxed-molecular clock method (only ostariophysan portions shown). Horizontal bars indicate 95% credible intervals of the divergence time estimates. ML reconstruction of ancestral habitats are indicated on selected nodes with pie charts showing the likelihoods for two character states (blue, freshwater; light green, saltwater). African characiforms and Big African clade in Siluriformes reported by Sullivan et al. [21] are denoted by "Af" and "BAf", respectively. All marine species are indicated by asterisks. Dagger symbols indicate the three big mass extinction events after 300 Ma. Paleocoastline maps [126] are shown below the timetree with moist zones schematically illustrated by green [127].
