Figure 6. Most parsimonious result from a phylogenetic analysis of discrete (1—64) and discretized continuous characters identified through gap coding (88—100). A, strict consensus of 30 most parsimonious trees with equally weighted characters (tree length 346). B, most parsimonious solution with implied weighted characters (k = 3) (tree length 27.86). Psammosteidae taxa in bold (for which quantitative characters have been treated as inapplicable, i.e. non-homologous).
