I found all of these myself and my friend helped me prep them as I had not done that before.
The Multi blocks of ammonites are Kosmeras Jason Maroconchs and Microconchs preserved in calcite and argonite Age...Middle Jurassic Callovian. Lower Oxford Clay..Peterborough formation wiltshire.
I have only just started learning about the geologly of fossils etc.
I started collecting
OOOPS!! again!! sorry for wasting all of your space here I am not to good at this forum lark yet.
The other Ammonite is as follows... Kepplerities Age...Middle Jurrasic Collovian 165 million years this time from the kelloway beds in wiltshire....this specimen is preserved as calcite.
I started collecting fossils some five years ago when I moved down to the very south coast of the U.K. with my family after a long illness...my collection was very crude untill I had the good fortune to hook up with someone who had more knowledge than me and some prepping tools! I do sometimes sell a few specimens on the markets down here in the summer, mostly single ammonites..the children like those best.
I have what I think is an interesting collection and will post some more pictures for you over the week end.
Phil, someone has justed opened their Tonmo account with a BANG !
Superb multi blocks

Sorry to sound like an anorak Michelle, but I have the prep bug (novice) so have to ask what kit you're using or I'll not sleep.
I use an Pneumatic Airscribe..Air Chisel...Dont know which type I have never looked to be honest with you. The Ammonite has plain old bee's wax on it. We use a lot of polishes and suchlike on the Ammonites.
Again, thanks for posting these stunning specimens. You've performed a fantastic prep job on them. Do you by any chance have any interesting photos of a Kosmoceras microconch with pronounced lappets? I couldn't spot any in the photo, but they could be there. That really would be quite something to find.
