FIG. 4 in A review of fossil Bursidae and their use for phylogeny calibration

FIG. 4. — Phylogeny of the Bursidae. Topology based on the multigene Bayesian analysis of Castelin et al. (2012); black dots (●) represent well supported nodes (posterior probabilities over 0.98) and white dots (○) represent moderately supported nodes (PP over 0.90). Bursa species in bold type are taxa that make the genus polyphyletic. Bracket on top indicates the phylogenetic extent of the genus Bursa if we consider the tubular posterior siphonal canal to be one of its synapomorphies, dotted bracket indicates the maximum extent of the genus considering the topology.
