A few recent mollusks from the Windom Shale

My spring visit to the Penn Dixie site near Blasdell, NY yielded some new mollusk fossils for me that I'd not found at the site previously.

First is this very delicate Paleozygopleura sp. gastropod. It's preserved on both sides of a very thin shale chip. the curved growth lines that can be seen are the tell tale sign of what this is.

Next up is a Paleoneilo emarginata next to a Rhipidomella penelope brachiopod

Lastly are these Nuculoidea corbuliformis

All three specimens came from the Bay View Coral bed in the Windom shale member of the Moscow Formation (Devonian, Givetian stage).
