Good idea to look for Afrotheria analogs.

Interesting grouping... what is the evidence for its monophyly?

Embrithopods outside Africa? Never read of that.

Creodonts... maybe _from_ Africa? Primates and non-crown-group metatherians
certainly to Africa. Ostriches IMHO _to_ Africa, via Europe and Asia from
India, as suggested in the paper on mtDNA phylogeny of ratites.

Sure? Not originally Outer Gondwanan?

The _basalmost_ known psittaciforms are from the Eocene of Messel and the
London Clay, though.

Any idea for or against columbiforms being the sistergroup to this?

I wait for more fossils of *Eremopezus*. Last we've read of it was that it
was not an aepyornithid and maybe carnivorous.
