I have had this specimen for 30 or more years in a disorganized collection of rocks, shells and fossils. I am not sure if I found this in 1983 on the coast of Oregon, near Newport (where I also found some Pelecypods), or if it was in 1988 in a dry creek bed in DeRuyter, NY (south of Cazenovia, which is South and East of Syracuse).
I thoroughly bummed that in my last and I hope final move this piece cracked and when I went to photograph it last night, it broke! Oh, and yeah, that is a golf ball I am using to show size, I couldn't find a single coin around! Photo #1 oblique angle, #2 birds eye view.
Any ID help welcomed.
