_Datousaurus_ is probably a euhelopodid, although it lacks the extra-
long neck of some other euhelopodids (like _Omei_, _Euhelopus_,
_Nuro_, _Mamenchi_) and (so far) no tail-club. The skull of _Datou_
is euhelopodid- like, and the chevrons are forked. _Datou_ is
possibly a basal euhelopodid. I wouldn't regard it as a cetiosaurid.
_Rhoetosaurus_ - well, according to Upchurch, the original paper by
Longman on this sauropod (written some time in the 1920's) alluded to
forked chevrons in the tail of _Rhoeto_. It may be a euhelopodid.
Upchurch regards it as Neosauropoda _incertae sedis_.
There are a couple of other Chinese sauropods of Early/Middle
Jurassic age that have been allied with _Shunosaurus_ - like
_Kunmingosaurus_, _Protognathosaurus_, and _Sanpasaurus_. But
they're all known from pretty scrappy material, and I couldn't begin
to guess what they are.
Finally, Eric Buffetaut referred _Phuwiangosaurus_ from the Early
Cretaceous of Thailand to the Euhelopodidae. It's teeth are more
slender than _Euhelopus_.
