All known confuciusornithids, that is, *Confuciusornis sanctus*, *C. dui*,
various probable synonyms of the former, *Changchengornis hengdaoziensis*
and *Proornis coreae*, are Barrêmian. Not sure for the latter, but the
layers are AFAIK thought to be continuous with Yixian.

Maastrichtian.

And presbyornithids (long-legged ducks, more or less) from the
end-Maastrichtian of both Antarctica and North America, AFAIK.
