Terry Dactyll Posted October 7, 2009 Share Posted October 7, 2009 Heres the other Nautilus I collected just over a week ago..... As bear pointed out to me, this shell must of been exposed on one side from the sediments on the sea bed, prior to fossilisation and then the shell rotted away..... Looking at where the calcite just stopped helped me decide which side to prep it from....presumably pointing me to the the underside, and once into the fossil, it was obvious it had undergone some compaction and distortion which broke the shell.... also the calcite when very thin.... but seeing I'd found it, carried it off the beach, and had put a few hours in on it, I continued the mission and made it into a displayable example... and its come out quite nice... Side prepped from Cenoceras obesum ....Sinemurian .....Lyme Regis.... Dorset Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
balanocidaris Posted October 7, 2009 Share Posted October 7, 2009 (edited) Really a GOOD, GOOD job... So the other side is the bad one, it isn't? At least myself, sure that I don't take home the original "stone"... Great work, congratulations. Edited October 7, 2009 by balanocidaris Link to comment Share on other sites More sharing options...

JohnJ Posted October 7, 2009 Share Posted October 7, 2009 Up to your usual high standards, Steve. Very nice! Each one you find has its own challenges...but it's clear that you up to them.

RomanK Posted October 7, 2009 Share Posted October 7, 2009 Hi Steve, you demonstrate so impressive result, it's just amazing! How you can deside what part has to be deleted and what retained? Are minerals of surrounded rock and fossil so different? How much time you spent to complete from the beginning? And my congratulations!

Terry Dactyll Posted October 8, 2009 Author Share Posted October 8, 2009 Thanks Guys & Fig .... balanocidaris....Thanks and yes... the other side was probably the upper surface, prior to fossilisation, and it hasnt preserved... Romank....deciding whats deleted and retained.... is a work in progress experience thing, maybe a bit of ''artistic flare'' as well ...... due to the nautilus rotting down on the upper suface, the sediments inside and outside the fossil that formed the rock are the same.... so only the surface of the fossils itself (the shell) has been rpelaced by a 2mm thick calcite.... so its this layer I work down to.... and theres no sepration layer.... the rock clings like superglue to the calcite, so the last bits I have to sand off with wet & dry sandpaper... This one took 23 hours to complete... Out of all the 'Good Stuff' I have sat there waiting to be prepped , this has landed on the bench because I dont recognise the rock layer its in, I think its a coroniceras of some description, but the rock itself looks different to the layers I normally collect.... I found it a coupler months ago and have been meaning to investigate it....you can see theres some restoration to one side required.... and Im still undecided which side to prep it from, this ones a gamble.... I'll let you know how I get on.... Thanks for your interest guys.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...

JohnJ Posted October 8, 2009 Share Posted October 8, 2009 Steve, you know I love your work, but I'm sure there are some folks looking at these last two photos and thinking "how the heck does he see an ammonite in that rock?" I can barely see a few small details that hint at the monster inside. Do those details show up better when the rock is damp? Thanks.

Terry Dactyll Posted October 8, 2009 Author Share Posted October 8, 2009 JohnJ.... Its not always raining over here you know ! . ... It does stand out a little bit better wet.... You can see the thickness of the shell I have to work with on this one and also the colour of the calcite (blacky yellowy) ..... But the rock is kind so far, the gamble is, if its all there or just a piece.... I dont profess to know anything about geology, but the limestone is different to my usual layer and I would call it fibrous, low in pyrite with few shelly inclusions causing me trouble (so far).... I managed to do 2 hours on it this afternoon.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
Terry Dactyll Posted October 10, 2009 Author Share Posted October 10, 2009 I couldnt find how to start a 'Blog'..... i clicked on Blogs, but there wasnt the 'new topic' button... so Ill just bang a few photos in here... Im 6 hours in now.... still only roughing rock off... but the fossil is starting to make some sense to me....showing the way it will display best....the shell is ultra thin... but were ok so far...

Terry Dactyll Posted October 13, 2009 Author Share Posted October 13, 2009 Ive found the end.... \o/... although still roughing rock off, doing the hardest side first....Its difficult exposing the keel as your working deep, which isnt evident from the photograph....probably another 2 hours to go on the keel....a chunk of rock popped off showing me some more of the ammonite on the 2nd whorl and it looks more calified towards the centre...... as I say, its new rock to me, and different to stuff Ive collected previously.... so im working blind.....and Ive cut a base deciding how it will display... its a heavy specimen..... Im about 12 hours in.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
