Figure 46 in The morphology and systematics of Mammalodon colliveri (Cetacea: Mysticeti), a toothed mysticete from the Oligocene of Australia

Figure 46. Most parsimonious optimization of select characters onto the phylogenetic hypothesis presented in Figure 41, showing the evolution of mysticete body size, and characters related to feeding and hearing functional complexes. Note that most morphological features implicated in bulk filter feeding evolve prior to the unequivocal appearance of this feeding mode. Taxa in bold represent toothed archaic mysticetes.
