The trouble is that there are so many definitions of "pseudosuchian" that I
really didn't know which one you meant(!).

In BCF, "protobird" is not "maniraptor," of course. "Maniraptor" is an
advanced stage of avian evolution, describing a theropod/bird with
flight-stroke forearms/wings (e.g., _Archaeopteryx_, _Deinonychus_, or any
modern avian for that matter). The "protobird" _Longisquama_ was nowhere
nearly that derived.
