Figure 20 in The interrelationships of Devonian lungfishes (Sarcopterygii: Dipnoi) as inferred from neurocranial evidence and new data from the genus Soederberghia Lehman, 1959

Figure 20. Unambiguous character changes mapped on one possible resolution of the clade above Stomiahykus and Uranolophus found among the 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. This topology places Melanognathus in a basal position relative to that shown in Figure 21, as the sister taxon of all lungfishes with the exception of Dipnorhynchus, Uranolophus and Speonesdyrion.
