Re: When New Met Papers

How solid are the arguments they bring up to ally it
with Protopteryx (and as per Theropod DB,
_Cuspirostrisornis_ and _Noguerornis_ ->

It is probably not the same as *Protopteryx*, to which it is apparently quite similar... but almost all of the characters emphasized in the abstract (and elsewhere) are plesiomorphic and/or indicative of immaturity.

It is most likely an "enantiornitine" bird in any case (spelled correctly everywhere except in the title and the running head).
