Protobird
The informal term "protobird" has been used by some paleontologists when discussing basal members of the clades Maniraptora or Avialae. All protobirds are extinct.
Protobirds would include animals like Confuciusornis, Sapeornis, and the Enantiornithes. These animals were small, flying, feathered, and closely related to birds. The term "bird", however, is often used more strictly to refer only to Aves.[1]
Gregory S. Paul originally used the term "protobird" in a wider sense in 1988, to refer to the extremely bird-like non-avian dinosaurs, including oviraptorosaurs, troodontids, and dromaeosaurids.[2] Paul speculated that these forms were so bird-like they probably had feathers, an idea later proven by fossil evidence.
