Just to add my two pence worth (and Byron is the one you need to get a reply from, may even be his youtube video), when it comes to the 'cracking' of a nodule there seems to be two main approaches that I've seen used, the dramatic split it down the middle with a good hard whack, maybe even using a nice big chisel, this is what I sometimes do when wanting to make a bit of a show on the beach if I'm leading a trip...! The second approach is the bit by bit one, slowly removing nodule to get an idea, then stopping and taking it home if it warrants it. Good luck! W.

Hi, been inactive for a long time, but I watched the Fossilsoft videos on Youtube, prepping Yorkshire nodules and I feel enthusistic again.

I have a question on prepping nodules, Yorkshire ammonites in particular. I have a number of nodules which are completely unprepped.

How do you decide where to start (I'm using a CP 'pen') if there is no sign of the ammonite on the outside? Most of the prepping I've seen, the nodule has been cracked open first, to see the lie of the ammonite. Is that usual?

Or do you just very carefully take off layer by layer until you find something and try and work out how to prep it from there?

Cracking nodules is common but look carefully to see if you can see any sign of the contents, A lot of nodules collected look promising but are barren so tapping is essential. If no sign on the outside I would usually tap on the beach since carting a rockery back to the car is unwelcome :)

Tapping can of course break the ammonite (assuming there is one in there) in two, so trying to work out the most likely orientation will help.

in most cases you can see the ammonite in the nodule,how do you know they have ammonites in them?
You can hit the nodule if you can't see anything,this can save time and effort but also damage the ammonite. i prep the out completely this preserves more of the detail.

If you think you have an idea that something could be there then use your pen to cut an x into the centre which shoud show you if anything is there.

Thanks for the replies. I should have been more complete. The nodules I am talking about were collected on the Yorkshire coast some years ago, mainly Kettleness and Port Mulgrave. I've been teaching myself to prep by cutting out some of the smaller ones and broken ones. The ones I have left are all quite large nodules, maybe 6" - 10" across. I gave one a 'tap' and it sheared right through two ammonites and a beautiful calcite belemnite. I was gutted.

Anyway, if that is the best way to do it, I suppose I'd better try again.

Cheers!

Similarly to the above I also try and hammer small chips off on site to check and to save any needless lugging of rock. one time I left my hammers behind because the amount of broken stuff was getting to be upsetting! now even if it does break, ive been lucky in glueing the bits back and prep from there.

Yes, I noticed the chap in the fossilsoft (don't know his name, sorry) videos seemed to do that a bit. I wondered if it was common practice. Ah well, I think I'd best get tapping.....

Thanks again.
