Figure 12. Strict consensus of the three shortest trees found in a PAUP analysis of the data matrix in the Appendix. Tree statistics: tree length, 55; consistency index (excluding uninformative characters), 0.80; rescaled consistency index, 0.69. Clades are diagnosed by the following synapomorphies (an asterisk denotes an ambiguous character; a minus sign indicates a reversal; numbers correspond to the characters listed in the Appendix): clade A (Captorhinidae), 1, 2, 3, 16*, 18*, 34, 35; clade B, 10(1), 14, 15, 17(1), 33(1); clade C, 5–11, 12, 19*, 31*; clade D, 4, 39; clade E, 13, 17(2)*, 20*, 21*, 25*, 29*, 38(1); clade F, 10(2), 22(1)*, 33(2), 40*; clade G, 38(2); clade H, 6, 7, 8, 9, 22(2)*, 23, 24, 26, 27, 28, 30, 32, 36.
