I would appreciate pointers to any info you (or others) have on early, non-computerized cladistic analyses.The idea of a synapsid-archosaur or synapsid-diapsid clade clade has a long history (Diaptosauria; early non-computerized cladistic analyses, etc.) And you can certainly pick out a few characters to support it (thecodonty, for one). But it doesn't pop out in the really comprehensive studies of Permo-Triassic critters.
Thanks, Joe
