Figure 3
Age estimates for major animal groups obtained under different assumptions about the age of crown-group Opisthokonta. Mean and 95% CrIs of age estimates for select nodes obtained with Calibration set A (see text) under the autocorrelated “ln” relaxed clock model using different root age priors – 1000 ± 100 Ma (lower bars), 1360 ± 100 Ma (middle bars), 800 ± 100 Ma (upper bars). Taxon names refer to crown groups. “Calc. + Homo.” = Calcarea + Homoscleromorpha clade. Dotted line indicates Precambrian/Cambrian boundary. Gray areas indicate Sturtian (left) and Marinoan (right) glaciations21.
