Hi all. I'm getting very bored now.  Found this in the shed. Is it worth polishing? If so, how do I go about it.
Thanks

Apart from the heading "Bradstock', you haven't stated where this was found. I'm assuming it's from Burton Bradstock, Dorset and in which case it's in Inferior Oolite matrix, which is not necessarily the easiest rock to prepare, as it will vary in hardness. Preservation of the fossils in IO are invariably quite poor and the 'rustic' nature of your specimen is quite typical. It will most probably have insufficient detail on it to enable any polishing (even though suture lines are visible) , or even cutting and polishing to show the internal details. However, it could be prepared, using an air pen, to a far better quality. 

The ammonite might well be better preserved elsewhere and preparation from the 'back' (i.e. not the eroded surface currently on display) might be possible, although there's a significant amount of rock to remove. Any preparation would be an easy enough job with the correct equipment but attempts using a hammer and chisel, Dremel engraver or similar, wouldn't give you the results that you might want. If you don't have an air pen and compressor, with suitable extraction facilities, you'd need to get it to a professional prepper, whose rates will vary. You should consider the expense of getting it done against the value of the specimen, which won't be very much I'm afraid. If it were mine, I'd probably get it better prepared in it's current position, extracting more of the fossil from the rock and ending up with a reasonable piece which you found. Hope this is of some help?
