*Palintropus* seems to be one. Unfortunately it's only known from a few
coracoid and scapular fragments.

of Luis M. Chiappe & Lawrence M. Witmer (eds): Mesozoic Birds. Above the
Heads of Dinosaurs, University of California 2002
Besides, Galliformes and Anseriformes are sistergroups, so, from the
presence of the latter, we'd expect the former anyway.

This one... there are only 2 possibilities: either it's a loriid, means, it
belongs to a _part_ of the crown group of Psittaciformes, or it's not a
psittaciform. The former seems quite unlikely, given e. g. the Eocene
psittaciform fossil record. There are many Cretaceous bird clades for which
we don't know dentaries, or which we don't know from the LK so far...
