I've just come back from a trip to Yorkshire where I managed to do a little fossil hunting and was lucky enough to find this ammonite. The problem is though is that generally the preservation in the area wasn't great and this one is clearly covered in a mudstone/ shale type of rock. However I think it might be worth trying to remove the surrounding rock because the small bit which I can see seems to have preserved fairly well. However I don't know the best way to remove it, see i'm not very comfortable with chiseling it away because I'm fairly new to this so would probably end up ruining it! I
