Figure 3.

Fossil-calibrated molecular phylogeny of the Branchiopoda. The BEAST tree is based on the combined first and second codon positions of the BUSCO nucleotide matrix containing 823 single-copy orthologs, constrained with eight fossil-calibrated uniform priors (red stars). Posterior probability values for all nodes are 1 except for the internal Chydoridae node (0.96). Blue bars indicate the 95% confidence intervals of the node ages. Black arrow below indicates the Permian/Triassic (P/T) boundary. Differences in topology from the RaxML-NG amino acid tree are indicated with asterisk.
