Hindlimb myology puts them next to... parrots.

Retroposons are "molecular morphology". Their presence & absence behaves like a morphological character, an idealized one in fact.

 Both radiations must have occurred in the late K. We have some
 fossils which very much look as if they'd turn out on one "side" of
 charadriiforms, Aequornithes etc. or the "opposite" one

Namely? Several have been proposed, but all are either too fragmentary to tell or have been removed from Neornithes. The latter just happened to *Palintropus* in the paper you mention at the end of your message.
