Here are the classic references:

Branson, C.C., 1964, Morrison fresh-water fauna in Wyoming, in Oklahoma
Geology Notes. v. 24, no. 10, p. 238-243.

Yen, T.C. and J.B. Reeside, 1946, Fresh-water mollusks from the Morrison
formation (Jurassic) of Sublette County, Wyoming, in Jour. Paleontology. v.
20, no. 1, p. 52-58.

Yen, T.C., 1952, Molluscan fauna of the Morrison Formation: USGS
Professional  Paper 0233-B


However, Emmett Evanoff of CU-Boulder is currently working on Morrison
gastropods (see the Morrison homepage at the address in my .sig).  I don't
have his email address (or even know whether he even has one), but you can
contact him through CU.

Steve Good at SUNY-Cortland is doing the freshwater clams and his email
address can be found on the Morrison homepage.  He can also point you to
good references on the molluccan fauna in general.  Tell 'em I sent ya.
