Fig. 8

Time-calibrated phylogeny of Bryozoa using MCMCTree based on the complete data matrix with posterior distributions based on the truncated-Cauchy priors. A time scale in Ma is shown above the tree, with geographical periods labelled below the tree. Node bars represent 95% confidence intervals of age estimates and raw numbers for mean. Numbered circles represent nodes with fossil calibrations, corresponding to the numbers in Additional file 1: Table S5
