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.

Diagonal hatching indicates damaged bone surface. Scale bar represents 20 mm.

Figure 24 in The interrelationships of Devonian lungfishes (Sarcopterygii: Dipnoi) as inferred from neurocranial evidence and new data from the genus Soederberghia Lehman, 1959

Figure 24. Distribution of cladogram lengths for the neurocranial data set for 1 × 108 randomly generated topologies. Arrow marked with MPT indicates the length of the shortest tree for the neurocranial data set (L = 125), while that marked with CB indicates the length of the shortest tree returning a topology consistent with the three-lineage scheme of Campbell & Barwick (1990; L = 143). These two cladograms are considerably shorter than most possible topologies, falling within the far left tail of the treelength distribution (the shortest 5% of all trees fall to the left of the dashed line marked with 95%). All other constrained topologies examined in this paper (monophyletic Chirodipterus: L = 137; monophyletic 'Chirodipteridae': L = 132; [Holodipterus + Griphognathus]: L = 133; monophyletic Griphognathus: L = 130) lie between the two arrows.

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.
