Figure 23. Previous hypotheses of early lungfish interrelationships. A, Campbell & Barwick (1990); B, Schultze & Marshall (1993); C, Schultze (2001); D, Ahlberg et al. (2006; strict consensus topology of the analysis of their total data set). Cladograms have been pruned to eliminate all taxa not included in this analysis in order to facilitate comparison with Figures 18–22.
