Phylogenetic Informativeness Analysis. Plot shows the phylogenetic informativeness of both mitochondrial loci used in this study through time. The grey shaded area represents the 95% HPD interval for crown Myxiniformes found in the tip-dated phylogeny where †Myxinikela siroka was used as a fossil tip calibration.
