Unknown find from beginner

[Zer0Sec]

Hey guys, I am new to fossil hunting but do have some amazing areas in the NE of England to visit. I found this at Saltburn beach last week and have been having trouble identifying it. Could you please help?

 

It's about the size of a small tangerine if that helps.

Looks like maybe banded flint?

I think it looks much more promising.

I don't think its banded flint. Maybe a rolled up trilobite in concretion.

I suspect an actual fossil as well but it is difficult to tell without further preparation.

 

It seems Saltburn is known for extensive Jurassic exposures from the Cleveland Ironstone Formation. I'd start looking for faunal lists for this and see what might match up.

It does look fossil like.  I was thinking of a part of a clam shell.  It could be almost anything and i am  not sure whether it can be prepped out.  Before i even tried to prep it what else did you see on site?  

[Ludwigia]

The best way to find out would be to get it prepped out of the matrix. It could be anything from the outer whorls of a fat ammonite to a bivalve or a large brachiopod. Certainly not a trilobite at any rate.

I think it's the keel view of a fat liparoceratid ammonite.

The nodule looks as if it's from the Staithes Sandstone Formation, which straddles the Middle/Upper Lias boundary of the Jurassic and occurs in the cliffs there below the Cleveland Ironstone Formation. 

Liparoceratids are scarce on the Yorkshire coast so it's a good find.

 

Something like this, though there are several possibilities and you'd need to see more of it for a precise ID.  From this excellent blog page.  (I can't remember if its owner is a member here)
