Platyceras sp. gastropod from the Kalkberg formation of New York

I've found a few gastropod fossils in the Kalkberg formation that are well preserved, which seems to be typical for most NY Devonian material. The below three specimens all appear to be Platyceras sp. with the first two looking very similar to each other.

Specimen #1

Specimen #2 - a part of the shell is broken and missing and that truncates the outer spiral.

Specimen #3 - This specimen is larger than the other two and may just be an older representative of the same species. The coil is covered with matrix so I can't see if it's similar to the other two examples.

All three specimens were collected from the same roadcut near Schohaire, NY from the Kalkberg formation (Devonian, Lockhovian to Pragian stage).
