Ammonite

Well preserved ammonites are usually found in hard limestone beds that are very distinctive. This example of Asteroceras is contained within an usual nodule and looks, perhaps, a little different from the classic Asteroceras obtusum. This is why we have put a question mark against the species name. It needs an expert to look at it.
