Figure 5 in Suction feeding preceded filtering in baleen whale evolution

Figure 5. Suction feeding precedes baleen filtering in mysticete evolution. A, consensus tree of aetiocetid evolutionary relationships, based on all cladistic studies published to date (e.g. Deméré and Berta, 2008; Deméré et al., 2008; Fitzgerald, 2010; Geisler and Sanders, 2003; Marx and Fordyce, 2015; Steeman, 2007), showing major feeding-related synapomorphies; B, life reconstructions (top) and skulls (in lateral view) of a representative archaeocete (Dorudon atrox), aetiocetid (NMV P252567), eomysticetid (Yamatocetus canaliculatus) and extant suction feeding mysticete (grey whale, Eschrichtius robustus); C, inferred behaviours and feeding strategies.
