Figure 19 in The interrelationships of Devonian lungfishes (Sarcopterygii: Dipnoi) as inferred from neurocranial evidence and new data from the genus Soederberghia Lehman, 1959

Figure 19. Unambiguous character changes mapped on one of 72 most parsimonious cladograms (tree statistics with no character ordering implemented: L = 125, CI = 0.5760, RI = 0.8094, RCI = 0.4662) retrieved from analysis of data derived from the neurocranial complex. Branch lengths scaled to the number of unambiguous character changes occurring along them. Phylogram is truncated above Stomiahykus and Uranolophus; two alternative resolutions for the clade above these taxa are given in Figures 20, 21.
