Hey, I just saw that a member of the Needmore formation in West Virginia and Pennsylvania is the direct equivalent of the Onondaga Limestone in NY.   I wonder if your fossil came from that, or a layer just above or below the limestone?


About your size.  The one I attached as the picture is the biggest one I’ve found.  Most of them are very small, like yours.
