Figure 4 in Phylogeny, taxonomy, and biogeography of the Sphaeriinae (Bivalvia: Sphaeriidae)

Figure 4. Fossil-calibrated phylogeny of the Sphaeriinae calculated under a lognormal relaxed clock model and a Yule process speciation implemented in BEAST 1.10.4 and obtained for the complete dataset of mitochondrial and nuclear sequences (16S rRNA+28S rRNA). Bars indicate 95% HPD of the estimated divergence times between lineages (Mya). Red numbers above the nodes are mean ages (Mya). Black numbers under the nodes are Bayesian posterior probabilities (BPP). Stratigraphic chart according to the International Commission on Stratigraphy (2022) (URL: http://www.stratigraphy.org/ICSchart/ChronostratChart2022-02.pdf). The node pies indicate ancestral area reconstructions of the Sphaeriinae clades (probability of each area combination) in accordance with the generalized biogeographic model (combination of the S-DIVA+DEC+S-DEC models).
