Critique | Carpenter (2001) coined Ankylosauromorpha for a clade linking Scelidosaurus harrisonii and ankylosaurs, a controversial arrangement supported recently by Butler (2005) but different than that found by Sereno (1986, 1999) and Norman et al. (2004). Carpenter (2001:455, 471) inadvertantly provided two stem-based definitions for this taxon, although stating that these were node-based (Carpenter 2001:455). If Sereno and Norman are correct, then Carpenter’s definitions (the two proposed) are either redundant with Scelidosaurus or have no taxonomic content. If Carpenter and Butler’s arrangement is supported, then the taxon is redundant with stem-based Ankylosauria, as defined here and by Sereno (1998). |
