Phylogenetic relationships and evolutionary change rates in Rhynchocephalia. A majority-rule consensus phylogeny after the morphological matrix from [23]. Phylogeny is time-calibrated with tip-dates and node ages are calculated under the ‘mbl’ model. Posterior probabilities are given for each node. Gray and white background stripes indicate epoch intervals within each geochronologic period. B Evolutionary change rates across Rhynchocephalia based on log-transformed character state changes per million years. Phylogeny is time-calibrated with tip-dates and node ages are calculated under the ‘equal’ calibration model. Gray and white background stripes indicate age intervals within each geochronologic period
