In our paper in Figure 34A and in the text (page 73), we incorrectly attributed a portion of the angular to the dentary as a process “ventral to the external mandibular fenestra,” as occurs in some crocodylomorphs. Th e dentary in Kaprosuchus lacks a posteroventral process and only has a posterodorsal process dorsal to the external mandibular fenestra (Fig. 1). Th e angular, which forms the entire ventral margin of the fenestra, is marked by a prominent ridge at mid length and is completely coossifi ed with the prearticular. Th is correction alters the scoring of a single character in our paper (character 181: dentary extension beneath mandibular fenestra; Appendix, p. 124). With Kaprosuchus correctly scored with state 1 (absent), rather than state 0 (present) as in the original Appendix (p. 138), our original phylogenetic trees (Fig. 43) remain unchanged. Tree length (985 steps), however, is one step shorter than initially reported (986 steps). Th e erroneous state had been interpreted as an autapomorphy for Kaprosuchus.
