)Cladistic analysis of outgroups Leonodus, Antarctilamna, and Phoebodus, and xenacanthiform genera represented by teeth plus other elements. As only 11 taxa were thus included, an ACCTRAN branch-and-bound search was undertaken using PAUP 4.0b10 (Swofford, 2002), all 19 characters unordered and of equal weight; multistate taxa were treated as uncertainty. The single shortest most parsimonious tree is 40 steps, CI = 0.7750, RI = 0.7632. Changes at nodes are listed in Appendix 2.
