Ambiortus is an extinct
Yevgeny Kurochkin in 1982.[2]
Classification
Ambiortus dementjevi belongs to
modern birds.[4] However, most analyses have found it to be either an unresolved member of the Ornithurae, or a more basal member of Ornithuromorpha. One 2006 study, for example, found it to be more primitive than Yanornis but more advanced than Hongshanornis, or even a member of the specific group containing both Yanornis and Yixianornis.[5]
The
cladistic analysis published in 2011, on the other hand, indicate that at least Apsaravis and Palintropus (which was mistaken as a much more modern bird initially) are very closely related.[7]
