NAmerican Paleogene fishes

[chartiem@xxxxxxxxxxxxxxxx (Chartier Michel)]

Dear colleagues:

	Could anyone refer me to the pertinent literature regarding
freshwater fishes of the North American Paleogene? I'm working on
early Eocene mammals of northwestern Wyoming, and have a couple of
fish fossils in my collection which I would like to identify 
(vertebrae mainly). I'm not well versed in the fish literature, so
any advice would be appreciated.
	I also have a few molluscs in the same collection, and I
would also appreciate some leads on the freshwater mollusc literature
for the same time/place.

Thank you for any help.
