I was thinking of such examples, and this is why I added "if both are= to be=20 defined". Most probably Lipotyphla and Archonta will simply not be de= fined,=20 simply because their contents are no longer thought to form one clade= each. (Wasn't Euornithopoda once such a case?

This is a case like *Euparkeria*. As I mentioned, cases like these sh= ould=20 (most probably) be explicitely allowed to stay, consistency with the= =20 literature outweighing the small possible confusion. --=20 Highspeed-Freiheit.
