Small inoceramus clam mold1

Inoceramus Clam Mold

These clams get quite large, but the outer shell is rarely preserved due the thin shell becoming easily destroyed over time. This leaves the inner mold. I found  this clam in the Duck Creek Formation along a feeder creek into Benbrook Lake.

NOT FOR SALE: Amphidonte Walkeri, FW Formation clam

This sizable clam exceeds 4 inches in length, and I have only found 2 over the last year or so. I have one available for sale but it is not listed anywhere and I haven't prepared it yet. The one shown is in my personal collection as of now. I'm open to offers, but it's rarely found so I am not sure if I'm willing to give it up absent more supply.
