Don't have any authors or date for an Omeisauridae (likely hasn't yet been 
created), but I have Mamenchisauridae Young & Chao, 1972. This would 
certainly have precedence over any recently created Omeisauridae. Also, don't 
necessarily discount the numerous strong apomorphies that unite Euhelopus 
with Omeisaurus and Mamenchisaurus. That bit of cladistics is probably wrong.
