Well, the exclusion of Anseriformes and Galliformes from Neoaves is well
supported on both molecular and morphological grounds.  But the cladistic
analysis of Bourdon (2005) found that the inclusion of odontopterygiforms
broke up Galloanserae in favor of an Odontopterygiformes+Anseriformes clade
(Odontoanserae).  It'll be intereresting to see what effect other putative
basal neognaths have on the Galloanserae (dromornithids, bathornithids).

But how Galliformes could be diversified after KT boundary - so, after Gondwanan and Lausaria break up - and even so have a cosmopolitan distribution? Would be ancestral galliform an efficient long-range flier?
