Any that is reasonably accepted (i.e. not beyond the
node uniting Archie with crown Aves). Senter finds
robust support for Ornithurae monophyly, but beyond
that things become more fuzzy. There is the
possibility that Sereno's Aves would have to include
_Epidendrosaurus_ too (given that it postdates Archie
and its Jurassic ancestor is not known).

Not to belabor the obvious, but you can't *find* Archie to be inside Archie+Neornithes.

I suppose the take-home message then is that _Epidendrosaurus_ is
weakly supported as outside, but close to, that clade.

Why can't you be a non-conformist just like everybody else?
