Re: Aliwalia [from Adam Yates]

No apologies necessary. Adam told me about Aliwalia months ago, so I had

OK, it makes sense now. Any word on what the "Aliwalia" maxilla belongs to?
(A rauisuchian, perhaps?)
Interesting that massospondylids, Yunnanosaurus and 'riojasaurids' have
been moved to basal sauropod status in Yates' latest analyses though. I
think that leaves plateosaurids as the only prosauropods (unless Efraasia's
position has stabilized), presumably with Saturnalia and Thecodontosaurus
still outside the Prosauropoda + Sauropoda clade.
If Prosauropoda is limited to plateosaurids (either completely or in
essence), I wonder if there's any point in keeping the term "Prosauropoda"
at all. Plateosauria or just Plateosauridae would probably be a better term
for this group, considering that the majority of taxa traditionally placed
in the Prosauropoda are now regarded as either basal sauropodomorphs or
basal sauropods. And the restricted composition of Prosauropoda sensu
stricto makes the name ("before sauropods") even more inappropriate than it
ever was. Just a thought...
