Talk:Avicephala

Creating an entire Wikipedia article for this clade may have been premature. Only 1 phylogenetic analysis has upheld this clade, while other more global data sets of stem-diapsid/diapsid reptiles have not recovered it, finding Coelurosauravus to be a basal neodiapsid, and drepanosaurids to be the sister group to kuhneosaurs, with both clades either being non-saurians or basal lepidosauromorphs. Drepanosaurids have also been reported as being primitive archosauromorphs This analysis used an only slightly modified version of Senter's data set and finds drepanosaurids as being archosauriform sister taxa, more derived than "prolacertiform"-grade archosauromorphs. Taxonomic sampling issues are probably at play in all three possibilities, but work by Müller offers the largest global solutions for addressing this problem.
