Hello, this is my first ever fossil find. I'm still trying to clean it, but it's quite large, and it's a very slow process.

I think it's a type of ammonite, but it almost looks like it's missing the shell, and the imprint of the flesh can be seen (looks like lobster meat to me). There is a small fragment of shell still on it towards the top right.

Any help identifying would be greatly appreciated. Click image for larger version - Name: large ammonite.jpeg, Views: 61, Size: 130.24 KB

Hi Hajicon and welcome.

That looks like a nautilus rather than an ammonite. It's a nice find, whatever; locality details would aid proper identification.

Hi CurtKnap, thank you for the welcome. I found it at West Bay beach cliffs in Dorset. I think I read somewhere that it's inferior oolite, although I know nothing about geology or fossils.

Most likely Cenoceras inornatum (Jurassic); google it and you should see some good examples for comparison.

I googled it and it looks exactly the same. Thank you for the ID. Any ideas on how to get the clay off? It's as hard as rock.

It likely is rock, rather than clay. The matrix can probably be removed manually, but not easy without damaging the fossil, and very time consuming. It would not be a difficult preparation job for someone experienced with appropriate air tools, but that would involve a cost - it depends how much value you put on your find.

Please get it cleaned up. A tidy Nautilus would be an envious addition to any fossil hunters collection.
