Critique | Chiappe (2002:457) coined the stem-based taxon Euenantiornithes for a ill-defined clade of enantiornithines closer to Sinornis santensis than to Iberomesornis romerali. This is a good example of a poor choice in a phylogenetic definition. All of the synapomorphies supporting this clade are in dsipute; the specifier Iberomesornis romerali has few, if any, autapomorpies that would allow reference of additional material, and the majority of enantiornithines are fragmentary taxa whose membership cannot be determined (Sereno et al. 2002). There is no solid case for the basal position of Iberomesornis, and thus no basis for knowing the taxonomic content of this taxon. |
