Avimimus of bird-like features not known in other dinosaurs at the time. In fact, Kurzanov argued that "Avimimus", rather than the famous early bird "Archaeopteryx", was close to the direct ancestor of modern birds, and that "Archaeopteryx" was not as closely related to birds as had previously been suggested. However, this view has not been supported by later phylogenetic analyses of dinosaur and bird relationships. Most modern scientists find that "Avimimus" in fact belongs to a diverse group of bird-like dinosaurs more primitive than "Archaeopteryx", the oviraptorosaurs. Kurzanov placed "Avimimus" in its own family, Avimimidae, in 1981. In 1991, Sankar Chatterjee
Archaeopteryx common uses of that term. A more thorough analysis was published soon after to test this hypothesis, and failed to arrive at the same result; it found "Archaeopteryx" in its traditional position at the base of Avialae, while "Xiaotingia" was recovered as a basal dromaeosaurid or troodontid. The authors of the follow-up study noted that uncertainties still exist, and that it may not be possible to state confidently whether or not "Archaeopteryx" is a member of Avialae or not, barring new and better specimens of relevant species.
