I mean no offense, but considering the relatively basal position of
Confuciusornithids within Aves relative to Palaeognathae, the presence of a
posteriorly forked dentary in confuciusornithids seems no more relevant to the
monophyly/paraphyly/polyphyly of Palaeognathae, than the presence of said
feature in oviraptorids.
