Fig. 4From: Phylogenomic analysis of Copepoda (Arthropoda, Crustacea) reveals unexpected similarities with earlier proposed morphological phylogeniesEstimated divergence times among copepods. BEAST2 (ver. 2.4.3) [56] is used with five calibration points (indicated by green circles, see details in Methods). Orange bars across nodes indicate 95% highest posterior density (HPD) of the Bayesian posterior distribution of molecular time estimates. The open and closed red circles (the parasitic and free-living forms of copepod fossils) above the branches show the oldest fossil records, most likely corresponding to the copepod orders [84–87]. The geologic time scale is according to the International Chronostratigraphic Chart (http://www.stratigraphy.org, v2015/01)Back to article page
