Mamenchisaurus (?) info

[Marco Auditore <maaudito@tin.it>]

Dear DML members,
I'm interested to know the actual status of the species Zigongosaurus 
fuxiensis and Omeisaurus fuxiensis. I know that (maybe) they are now 
referred to Mamenchisaurus, but is not clear to me if they are based on the 
same type species or not. I've found that the describers are different for 
the two taxon, Z. fuxiensis Hou, Zhao et Zhu, 1976 and O. fuxiensis Dong, 
Zhou et Zhang, 1983. And, if they are not the same beast, the occurence is 
the same? And the etimology for the word "fuxiensis"?

Finally I need any info about Omeisaurus zigongensis Tanimoto, 1988.

Thanks in advance
Marco
