Stopped off at Aust on way home today and found a couple of bits if anyone interested to see.
1st pic - ichthy vert
2nd pic - half an ichthy vert
3rd pic - coprolite
4th pic - bit of bone bed with few tiny teeth in it
5th pic - think it's a vert (broke the corner off trying to expose the side!)
Cheers

Nice finds! I think you’re right on the ichthyosaur very ID for 5. Wow that bonebed is stuffed full of shark teeth! I think they’re mostly lissodus minimus. If the bonbed has no bone, then have you ever thought about processing it? However it’s a nice display piece as it is but if you prefer out-of matrix teeth, then you could give it a try. Beware! They are very delicate!

Al,

Thanks! Yes for the last fossil I've looked at the structure where I broke it and it's quite hard to tell it's bone. I think it is, just looks quite crystalline that's all. The teeth are quite interesting, thanks for the ideas, will have a think what to do with that one! Cheers

Hi Matthew,pic 5 certainly looks like a beach/weather worn icthy vert the matrix and bone are equally very hard,best never approach with chisels unless they are on the end of an airpen. You are probably knocking on the door to invest in the preparation kit or hold on to potential fossils in matrix until you can get them prepped accordingly.
That said though my early years of prepping was to cut down and near the fossil with a hand disc cutter (diamond disc) as much as you dare,finish off with a dremel or such like with diamond coated bits, some tungsten carbide/tile grinder bits will shift softer natrix.
Everyone who prepps have there own way of approach "what work s best for you" is a common phrase when you talk to fellow collectors/preppers.
Matthew if you are planning some more visits locally (chepstow) im happy to look at find pic 5 with a view to prepping it for you, have you glued it back together or just placed back in for photo shot?

As you know a lot of my finds have been donated on hopefully to the greater good! with benefit to all,however i still have examples similar to pic5 which if prepped from the other side can turn out a pleasing result.

this one is similar to yours also an aust find not prepped yet maybe a reverse prep for this one!

this one is aust to from a recent fall you can imagine if left to the elements it would quickly wear down level with the matrix, no reverse prep hopefully this time!

I hope this helps you with what to do with future finds,only my opinion of course experience has taught me valuable lessons i have damaged so much in the past and occasionally still get it wrong!

Hi Richard,
Many thanks for your replies on both this thread and the Lavernock topic. Wow that's very kind of you to offer to help prep that vert, thanks! Yes I quickly realised that my approach with the hammer and chisel wasn't the best haha. I haven't glued the broken bit back on yet (the broken bit has actually broken down further unfortunately). Some great pics there you've posted, especially like the second one. Also the last vert, you've a keen eye, I would never have spotted that one! Kind of you to offer to help with prep, but I worry it would be a big task!! Still keen to visit Sedbury at some point also. Hope you've had some good finds recently. Cheers

Hi Matthew
Most of us have buggered up stuff it takes a while to resist the chisel the shock waves can make bone/matrix pop off almost anywhere on a hard surface, with a large block sometimes you have to take the risk to reduce weight and size to get it home,i'm assuming this was on site and not at home. anyway the offer to give it a possible presentation is there..nothing to lose unless its fractured beyond comprehension!...certainly the 2nd pic is more appealing than the other side pic 1,this is what one would aim for in prepping your vert.
just let us know when you have ample time for sedbury opportunity for me to see the prep task if you wish to give it a try....plus if you want an insight into the prep process and the tools for future pondering ur welcome.
P.S what do you think of the original method of prepping (disc cutter and dremel) probably quite a few still at it this way?

Hi Richard,
I actually did the damage at home believe it or not! When I found the rock I almost put it back on the beach because I didn't think it was anything. Then looking at home with my lens (10x magnification) the exposed edge of the vert still didn't look like bone, so I thought I'll give it a whack with hammer and chisel before I chuck it out in garden haha!
I would be very pleased to see Sedbury and learn more about prep process, many thanks, will drop you a message with view to coordinating something. Would be fantastic to prep that fossil too, although I don't want to take up too much of your time! Will have a look into different prep tools.
Cheers

Hi Matthew, 
arrh perhaps if you did it on the beach it would still be there so theres a positive to take out of it all,👍 message phone best idea i will see that asap! definitely be beneficial to physically see a few prep tools especially in action looking at images and reading all the jargon on them all a bit hit and miss, u can usually end up buying a make do tool and soon after forking out again because it has limited operations, but as said dremels will do a job but when you see airpens and grinders at work you will see how refined the process is and has to be on some fossils if you want them to turn out satisfactory.... when it comes to a chisel approach go a little pro/specialist which i will be able to show you its basically a very slimline long handle with an airpen chisel stylus on the end that would be kinder at nibbling down the side of a fossil to investigate with minimal damage, apologies on realms of info but handy to others to read and make the right choices too!, 
regards rich
