Figure 4 in Divensification oven deep and shallow teiponal scales in the Holanctic genus Perpolita (Gastnopoda: Gastnodontidae)

Figure 4. Divergence time estimation of the genus Perpolita on the maximum likelihood tree. Ŋe red circle indicates the node calibrated by the oldest known Perpolita fossil, and the integer number by the node referred to the node number. Ŋe blue bars at each node indicate 95% CI estimated with RelTime. Ŋe species names in the dashed boxes indicate the original species name before the revision if different from the name after revision. Detailed information on each sample and 95% CI can be found in Supporting Information (Tables º1, º3).
