Comments | Ornithothhoraces was first used as a label on a cladogram in a figure by Chiappe and Calvo (1994:fig. 9). Chiappe and Calvo (1994), thus, are properly credited with the name. Padian (2004:tab. 11.1), however, incorreclty cited Chiappe (1995) as author of the taxon. Later Chiappe (1996:205) explained that Ornithopectae, the previous taxon he had coined for the same clade, should be dropped because Ornithopectae was “grammatically incorrect.” There was no further explanation. Chiappe (1996) then proposed a definition that is a textual variant of the first definition for the taxon, which appeared earlier in a figure legend (Chiappe 1995:fig. 1). Padian et al. (1999:75) proposed a definition for Ornithothoraces, but this definition is a textual variant of that in Chiappe (1995), which was not cited. Sereno (1998) used the better known Sinornis as an internal specifier, which was followed by Senter at al. (2004:19). The active definition is a first-order revision of Sereno (1998), using Sinornis santensis as a specifier within Enantiornithes because of its completeness and nested position (Sereno et al. 2002). Iberomesornis romerali, by comparison, is based on a single partial postcranial skeleton that has been subject to alternative osteological interpretations(Sereno 2000, Sanz et al. 2002) from those in its original description (Bonaparte et al. 1988). |
