It hasn't. At least I haven't been able to find a citation that wasn't 'in

Hey, that last one may be right! If silesaurids are indeed basal
dinosauromorphs (or dinosauriforms), and are closer to ornithischians than
to other dinosaurs, then the Dinosauria would include silesaurids. In the
even remoter possibility that the other two are also correct
(theropods-from-shuvosaurs, sauropodomorphs-from-basal archosaurs), then
Dinosauria would still remain monophyletic, courtesy of its definition - it
would just be expanded to include most of the Archosauria!
Technically true, but I think it'd be time to drop the name if Dinosauria
included crocodillians. Despite the fact it has priority over
Incidentally, I don't find it too improbable that one or more currently
non-dinosaurian groups will end up inside Dinosauria. Whether it be
silesaurids, Marasuchus, Pseudolagosuchus/Lewisuchus, etc.. Most of the
relevent analyses have used very low amounts of taxa and characters.
And even the suchian thing seems possible if croc-type ankles are primitive
for Archosauria and several groups evolved mesotarsal joints independantly.
I already find it likely pterosaurs did.
I know Jalil and Knoll (2002) put _Azendohsaurus_ outside the Dinosauria,
but do they (or Parrish) say what it might be.
I don't think Jalil and Knoll did, though I have some good photos of their
poster I can't distribute. :)
