The nearby discovery of the primitive bird "Vorona berivotrensis" shows that the possibility of a mix-up cannot be entirely excluded. However, many other scientists, including the original describers of "Rahonavis", think its remains belong to a single animal. The wing bones are close to the rest of the skeleton. All the bones attributed to "Rahonavis" were buried in an area "smaller than a letter-sized page", according to co-describer Luis M. Chiappe in his 2007 book "Glorified Dinosaurs". Chiappe maintained that "Rahonavis" could probably fly, noting that its ulna was large and robust compared to "Archaeopteryx", and that this fact, coupled with the prominent quill knobs, suggest that "Rahonavis" had larger and more powerful wings than that earlier bird. In addition, "Rahonavis" shoulder bones show evidence of ligament attachments allowing the independent mobility needed for flapping flight. Chiappe concluded that "Rahonavis" was capable of flight, though it would have been more "clumsy in the air than modern birds".
