In Adam Yates' post on this publication, he said Avemetatarsalia was
equivalent to Ornithosuchia, a stem-group. Does the paper specify
whether
its definition is node- or stem-based?
--------------------------

I don't have the paper with me but I'm sure it was a stem-based definition
(ie all taxa closer to birds than to crocs). So it is equivalent to
Gauthier's Ornithosuchia (and if you adhere to strict priority it is a
junior synonym) but doesn't have the problem that the higher taxon doesn't
contain it's nominal taxon.
