        Hou, Zhou, Martin, and Feduccia attribute _Liaoningornis_ to the
"Ornithurae", and specifically imply that it is *not* an enantiornithine.
        They also state (incorrectly) that Chiappe uses Enantiornithes as a
parphyletic grab bag, and seem to think that *they* are the ones proving its
monophyly.

        Also, to whomever suggested that the AMNH "oviraptors" were
_Ingenia_: If you watch closely during the National Geographic Explorer
footage of these critters, you will see that the manus of at least one of
the new animals does not show the distinctive morphology of _Ingenia_.
Unless that morphology is sexually dimporphic, these specimens are not
likely to be _Ingenia_. They could be a dimorph of _Oviraptor_, or they
could represent _Conchoraptor_ or a new taxon.
