I found this fossil on Filey Beach, North Yorkshire, UK. On the outside, what I assume is a large belemnite is visible. When I cracked it open, instead of finding a long, pointed end, I found a bulbous rounded end. This appears to be where I thought I would find the end of the belemnite. Could anyone ID it for me? Also in the rock was a good sized ammonite but this was separate from the pictured fossil.
Thank you for your help.
