Critique | Chiappe et al. (1999:3) coined Ornithuromorpha in the abstract of a monograph on Confuciusornis; he neither discussed it further in the text nor proposed a definition. Chiappe (2001:126) provided a node-based definition using Patagopteryx, Vorona, and Ornithurae as specifiers. Because he regarded all of these taxa as closer to Neornithes than to Enantiornithes, this new taxon has the same taxonomic content as Euornithes. Ornithuromorpha, nevertheless, is not a junior synonym of Euornithes, because the former is node-based and the latter stem-based. More recently Chiappe (2002:457) dropped Vorona from the definition presumably because the incompletely known Vorona is positioned by some within Enantiornithes. The current utility of Ornithuromorpha is questionable. If Vorona is placed within Enantiornithes, then Ornithuromorpha would constitute a junior synonym of Ornithothoraces. |
