I wasn't referring to the entire Theropoda.  When I said I "non-neornithine 
birds", I was referring to a PT paper that was narrower in focus, and was 
dedicated to *just* non-neornithine birds.  All those names for basal 
avialan and non-neornithine clades confuse the bejesus out of me: 
Ornithuromorpha, Ornithothoraces, Pygostylia, Ambiortimorphae, Carinatae, 
Euornithes, Enantiornithes, Euenantiornithes...  For example, I've seen 
Euornithes used in two different ways, by Sereno (1998) and Kurochkin 
(1996), with the latter using Euornithes to name a clade within the 
Enantiornithes!
