Catalog Number: CG-0025

This is by far the largest identifiable Cephalopod body chamber I have found to date. It came out of the hillside as a boulder but had a familiar body chamber shape. I can identify it as a cephalopod, but I am unsure of the species. The best guess is Solenocheilus. In correspondence with Royal Mapes from Ohio University in talking about Solenocheilus, he mentioned he had seen some that were “nearly 10 inches wide and 12 inches in diameter”. There are not many other species that could come close to being this big. This particular specimen measures 5.5 inches wide by 9 inches long.

As usual, a specimen this large is also very fragmented and hard to see detail past what you can see in photos below.
