Although talking with some people today I've learned that there are
supposed to be some pretty good fossils of shorebirds and anseriformes
from the Cretaceous- Presbyornis like stuff, for example, so maybe quite

that would imply a substantial diversification already, it being an
anatid- I'm gonna remain undecided on this one until I see some papers...
