Not Mesozoic, but the new issue of JVP has a number of articles about
new discoveries of the Pelagornithidae.

ABSTRACT
We describe new avian remains from the middle Eocene of eastern
Ukraine. The material includes well-preserved bones of a small species
of Pelagornithidae (bony-toothed birds), which was tentatively
identified as Odontopteryx toliapica in an earlier study. The
Ukrainian pelagornithid is, however, distinguished from this species
and other early Eocene pelagornithids in several features, and we
describe it as Lutetodontopteryx tethyensis, gen. et sp. nov. The new
material includes the most complete pseudodentition of a small
Paleogene pelagornithid, and details of pseudotooth morphology
strengthen previous assumptions that the pseudodentition of
pelagornithids derives from tooth-specific developmental programs and
is homologous to true avian teeth on a molecular level. Most major
postcranial bones of L. tethyensis are represented by well-preserved
bones, and in some derived morphological features the Ukrainian
species agrees with Neogene pelagornithids but differs from the early
Eocene Dasornis species. We also report a partial sternum of a much
larger bony-toothed bird, which resembles the sternum of the middle
Eocene Gigantornis eaglesomei. We further describe previously unknown
skeletal elements of the loon Colymbiculus udovichenkoi (Gaviiformes),
which show that this species substantially differs, in both wing and
leg morphology, from the well-known gaviiform stem-group taxon
Colymboides.
