Comments | Makovicky et al. (1999) provided a phylogenetic definition for a taxon originally erected as a subfamily by Bonaparte (1999) for Unenlagia comahuensis (Novas and Puerta 1997). The intention of the initial definition provided by Makovicky et al. (2005) was to unite Unenlagia with other southern forms such as Buitreraptor and Rahonavis. The analysis shows only a weak association among these taxa; other authors have placed Unenlagia and/or Rahonavis closer to Aves. The active definition, therefore, places additional constraints on its potential taxonomic content (by including three additional external specifiers) to ensure that it does not include Aves or subsume another dromaeosaurid taxon of equivalent Linnean rank (e.g. Dromaeosaurinae, Microraptorinae, Velociraptorinae). |
