Figure 6

Fossil calibrated Bayesian phylogeny of 7 Cuvierina and 6 outgroup taxa using COI (658 bp) and 28S (989 bp). The reconstruction was calibrated by the earliest occurrences in the fossil record of Camptoceratops priscus and Cuvierina torpedo, indicated by green dots on the nodes. Numbers above major branches indicate posterior probabilities (only values >0.95 are shown); numbers below major branches indicate ages in million years ago. Branch widths correspond to substitution rates, with thick branches indicating high substitution rates. Symbols for Cuvierina indicate major genetic clades; colours indicate morphotypes (also see Figure 5). Image of C. priscus: [85]; and C. torpedo: [76]. The TTE and IOP are highlighted after estimations by [86].
