Talk:Archaeornithes

Cladogram irrelevant
The subclasses Archaeornithes and Neornithes do not appear in the cladogram, so the viewer has no idea where Archaeornithes appears in the pylogeny of birds or their dinosaurian predecessors. I'll fix it when I have time. Sbalfour (talk) 21:08, 22 December 2016 (UTC)
