Subgroups

Aveairfoila is a clade of maniraptorans that contain the therizinosaurs and the pennaraptorans the latter which includes birds. The group was coined by Gregory S. Paul in his second edition of the The Princeton Field Guide to Dinosaurs. In his concept Paul argues therizinosaurs and oviraptorosaurs are closely related to Jeholornis and omnivoropterygids respectively, which are usually considered to be avialans, and that therizinosaurs and oviraptorosaurs are neoflightless birds. His evidence is based from observations in the sternum and rib morphology.[1] This is not the first time he proposed these claims as Paul made similar claims regarding the entirety of Maniraptoriformes.[2] Paul's taxonomy is not accepted by most scientists as often they lack any sufficient explanation or citation.[3] Regardless the name is useful to describe the clade that contains therizinosaurs and pennaraptorans as there are a lot phylogenetic support for the two taxa being sister clades.[4][5]
