I agree that Eobrontosaurus is a controversial (and IMHO unlikely) genus, but it is NOT Camarasaurus. It is an apatosaurine diplodocid. Please, please, please everyone, go take a look at it yourselves if you don't want to take my word for it (certainly don't rely upon the type description!), but it is clearly a (largely unprepped) apatosaur.

There's also _Suuwassea_ (you'll kick yourself for forgetting that one). Plus some sauropod genera of controversial validity, like _Eobrontosaurus_ (?=_Camarasaurus_) and _Dystrophaeus_ (possibly a nomen dubium). _Dyslocosaurus_ might be from the Morrison. I don't know what to make of _"Apatosaurus" minimus_.

Probably a nomen dubium. It's a shame that a potentially iconic name like "Palaeopteryx" was squandered on indeterminate material. Interestingly, the name is not registered at Nomenclator Zoologicus. 
 
How many specimens of 
Marshosaurus are known beyond the type and the referred partial
skeleton? 
 
Just those two, AFAIK.
