Comments | Chiappe et al. (1999) defined Confuciusornithidae as a node-based taxon including two closely related species, Confuciusornis sanctus and Changchengornis hengdaoziensis. It seems unlikely that Confuciusornithidae will ever contain dozens of genera, using the aforementioned definition. It seems much more likely that additional species or an additional genus and species will appear in the lakebed sequence in China that is the sister taxon to these two closely related species. In that case, there will be an unnamed clade consisting of Confuciusornithidae plus this new speices. To maintain the taxon name for the entire stem, the active definition is a second-order revision. Like other low-level taxa with few species outside Neornithes (Hesperornithes, Hesperonithidae, Archaeopterygidae), this definition will accommodate present and future closely related forms. |
