Well, yes, but then you also have to exclude the afrothere ungulates.
And where are notoungulates coming out these days? I have no idea.

"Ungulate" is really more of an ecomorph than anything else, it seems
to me. And if some "condylarths" are stem-placentals (as Tom Holtz
mentioned), then that's yet another case of this ecomorph arising
independently.

I've gotten the paper from a couple of people now -- thanks!
