Figure 18 in The interrelationships of Devonian lungfishes (Sarcopterygii: Dipnoi) as inferred from neurocranial evidence and new data from the genus Soederberghia Lehman, 1959

Figure 18. Hypothesis of early lungfish interrelationships based on maximum parsimony analysis of data derived from the neurocranial complex. Strict consensus topologies of 72 most parsimonious cladograms (tree statistics with no character ordering implemented: L = 125, CI = 0.5760, RI = 0.8094, RCI = 0.4662). A, strict consensus topology; B, strict reduced consensus topology pruning Melanognathus and 'Chirodipterus' liangchengi from all constituent cladograms; C, strict reduced consensus topology pruning Melanognathus from all constituent cladograms. Numbers below nodes in A represent Bremer decay indices and bootstrap values (where the latter are greater than or equal to 50%).
