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.
