Summary of MCMC samples for node ages (means and 95% credible intervals) in the independent-rates (IR) and autocorrelated-rates (AR) analyses using MCMCTREE-HS [63]. Results from the two data sets (12nRTn and 123a) are shown separately. For node numbers, see tree at the end of this file.

Timetree derived from the Bayesian relaxed-molecular clock method (non-ostariophysan portions also shown). Upper (maximum) and lower (minimum) time constraints used in this study are shown by arrowheads with corresponding nodes connected by dotted lines. All marine species are indicated by asterisks.
