condition, found in basalmost forms (_Shunosaurus_),
euhelopodid/mamenchisaurids (_Omeisaurus_, _Euhelopus_: like Dinogeorge, I
wouldn't be surprised if Euhelopodidae really does contain _Omeisaurus_,
_Euhelopus_, and _Mamenchisaurus_), _Jobaria_, and basal macronarians (i.e.,
The weird skulls are all in the diplodocoids and the titanosauriforms.
