Terry Dactyll Posted October 13, 2010 Author Share Posted October 13, 2010 (edited) Tim..... I didnt personally find this one I 'traded' for it.... one carb exposure I collected yeilded quite an abundance of material and I offloaded some in exchange for this.... you can see why huh ... It was prepped by a guy in the UK who has had many years experience and turns out some beautiful stuff....he also sells prep equipment and has a website.... http://www.kenmannion.co.uk/ So to answer your question I dont know how long it took and I 'think' the rock was split into 2 pieces using a stil saw and then wedged apart with chisels and the most populated half was prepped ( I'm only guessing)...... the unprepped rock itself did the rounds and was back and to between a couple of preppers exchanging hands for a few hundred pounds each time and eventually Ken Mannion sat down and tackled it.... I was told by a very good source it is the most 'densely populated' chunk of semicostatum zone to come off the Holderness coast.... I've never seen another to make me think any different.... I have a similar chunk of exactly the same ammonite from Lyme Regis, Dorset....one day I will try and tackle it.... PS... I get your question now... every single rib on every single ammonite would of contained matrix.... they are quite 'sticky' so a lot of rock....

Terry Dactyll Posted October 21, 2010 Author Share Posted October 21, 2010 This is the one with the ammonite patina on.... This shells beyond pretty.. .. its absolutely beautiful, loaded with pyrite, black calcite with touches of mahogany… Its only the 2nd of this species I have come across Coroniceras reynesi, 16 “ Lyme Regis...

Terry Dactyll Posted October 26, 2010 Author Share Posted October 26, 2010 You cant see the pyrite with the poor lighting today it just looks jet black so the picture dont do it justice....Coroniceras reynesi Lyme Regis Dorset And another rock landed on the table, I wonder what could be inside... it has a big chunk of wood on the back, but I think im going to have to lose it to get some weight of the finished shell...

Plantguy Posted October 31, 2010 Share Posted October 31, 2010 Hey Steve, looks like those darn cephalopods are continuing to keep you very busy! Very nice new material/photos! I dont remember asking or seeing...Do you have any with predator or congenital anomalies or the so called dreaded after death limpet damage that I read about recently? Keep up the stellar work!

Terry Dactyll Posted October 31, 2010 Author Share Posted October 31, 2010 Chris.... I have had quite mild pathalogical deformities on a few shells resulting in changes in rib sizes etc... with the most obvious being this one on the upper RH edge of the outer whorl.... I dont have this shell anymore I had to trade it in to aquire something rarther special plus some other stuff... Its the one I liked the least at the time ... Collection needs must etc etc.... So if anyone owns it (sorry for posting a photo of your shell) Preditory marks.... not that I'm aware of (bitemarks as such) although I always thought the mouth of this 22" North Somerset Coast Vermiceras was a very strange shape as if something had surgically removed the critter from the shell... I havent heard of the afterdeath limpet damage so maybe you can expand on this... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...

I havent heard of the afterdeath limpet damage so maybe you can expand on this... Hey Steve, thanks for the additional photos. Always wondering how things got that way--quite fascinating! On the limpet damage, I read a discussion somewhere (my darn "i" key keeps sticking/dropping letters--UGGH!) ...anyways, apparently folks were looking into mosasaur bite damage on ammonite shells and based on some lack of radial cracks around holes thought to be caused by these predators piercing teeth there were other ways to have holes show up in ammonite shells. It was being proposed that limpets had somehow attached themselves to dead ammonites on the floor bottom and those attachments had formed holes/degraded the ammonite shells in spots and their subsequent burial/preservation resulted in complete holes in ammonite shells formerly attributed to bite marks. Not sure there was a final word on this discussion or if both scenarios do exist in current thought. If I find those docs I'll shoot you some links....Could be one of the legions of our ammonite lovers on the forum can provide a link to a full document. So many these days require subscriptions to see more than just the abstract! Enough of the ramblings from plantguy....gots to go mow the yard and do my chores! Thanks again for the extra photos!

Terry Dactyll Posted November 1, 2010 Author Share Posted November 1, 2010 Chris..... Cheers for bringing it to my attention.... I did a bit of googling and found out more... the gradual application of pressure from the jaw coupled with the internal 'stiffening' of the shell by the sutures (flotation chamber walls) results in the shell being pierced and not shattered.... leaving the holes you describe... Limpits can wear away certain areas as you see on the rocks where you go fossiling by the sea... very possible both scenarios happened, with the first one being more commong Ider thought.... SharkTeethCollector.... Thanks... They are nice shells and the finished fossil is well worthy of the effort in my books... beckman.... a time machine.... Now that would be intresting...
