Here are some pelcypods from the Windom shale member of the Moscow formation of New York.
Grammysioidea arcuata from near Eaton, NY
Cypricardella bellastriata from the Lake Erie shoreline
I am not entirely sure of what genera this shell is, but I found it near Tully, NY. It looks like an internal mold of possibly a Paracyclas?
Palaeoneilo emarginata found at Tully, NY
A closer view
Note the casts of a bryzoan (likely Hederella sp.) that are preserved with the exterior mold of the shell. From the view I see it looks as though the bryozoan was growing on the outside of the shell.
The Windom shale is a part of the Moscow formation and is just below the Tully Limestone which marks the boundary of the Givetian/Fransian stages of the Devonian in New York.
I used the book "Geology and Paleontology of Eighteen Mile Creek and the Lake Shore Sections" by Amadeus Grabau, 1898, Buffalo Society of Natural Sciences, to help ID these fossils.
