A question about Mickey's non-theropod tree

[Jean-Michel <s.aegyptiacus@wanadoo.fr>]

 Hello all,
 I've been offlist quite long and surely missed some important points. I
just
 took a look at the non-theropod part from HP Mickey Mortimer's site, and I
 saw that Mesosauridae were tentatively put within Diapsida along with
 Claudiosauridae and that Anapsida is part of Achosauromorpha. Did I really
 miss some important points or is there new evidence for these taxa?

 Sorry if this has already been clarified

 Cheers,
 Jean-Michel
