Re: [dinosaur] Diadectomorphs and seymouriamorphs as amniotes from inner ear morphology

> Absent better agreement on lissamphibian origins, would the amniote total group be a terribly useful thing to have a name for?

Perhaps not. Specifically, if the lissamphibians belong with whatever remains of the "lepospondyls", then the seymouriamorphs are not even crown-group tetrapods unless the new paper (which I haven't read yet) finds something else.

> I was surprised, BTW, to see "non-crown amniotes" in the abstract - is there any possible distinction from "stem amniotes" (which they also use)?

No.
