There's still a use for _Pan-Serpentes_, then.

In Joyce et al. 2004, _Testudinata_ is defined as an apomorphy-based =
clade:

In the same paper, _Pantestudines_ is proposed as the panstem. _Anaps=
ida_ and
_Parareptilia_ are listed as synonyms.

But certainly not the name of the panstem. The panstem has been calle=
d
Ornithosuchia (invalid by PhyloCode rules, since it does not include
_Ornithosuchua_) and (I think) _Ornithotarsi_. Both the panstem and t=
he crown
have been called _Aves_, but using it for the crown is much more comm=
on.

If _Craniata_ is stem-based (_Amphioxus_ and _Tunicata_ as external
specifiers?), it would count.
