A new paper and taxon (Brodavis) out for a few weeks but not yet
mentioned on the DML:

A new evolutionary lineage of diving birds from the Late Cretaceous of
North America and Asia.

A new family, Brodavidae, with one new genus and four species, is
described from the Late Cretaceous (Maastrichtian) of Asia and North
America. These include the first freshwater occurrences and latest
records of the order Hesperornithiformes, an extinct group of diving
birds whose marine members had probably lost their powers of flight by
the end of the Early Cretaceous. Minimal pachyostosis in the
freshwater form suggests the possibility of volant abilities.
