Terry Dactyll Posted November 5, 2009 Share Posted November 5, 2009 Ive just finished prepping this 15" er .... and was quite supprised to find quite a bit of Pyrite (fools gold) attached to the ammonite around the outer whorl.... when it come to prepping pyritic fossils I did hear that inhaling the dust of iron pyrite can mix with moisture in your body and lungs and form an acid and cause quite a bit of discomfort.... so I made sure I wore my mask at all times fitted with decent organic filters.....has anyone else heard this ?.... I didnt know if the pyrite would show through to well after it was waxed so i took a photo of a section of it before to compare....considering the bad lighting due to the rain its come through ok.... and.... Please do show us your Pryite ammonites... Id love to see them..... Coroniceras Charlsei 15"....Sinemurian... Lyme Regis 1 Cheers Steve... And Welcome if your a New Member...

tracer Posted November 5, 2009 Share Posted November 5, 2009 haven't heard it but it makes sense that FeS2+ your breath would equal H2SO4 + your discomfort. Link to comment Share on other sites More sharing options...

RJB Posted November 5, 2009 Share Posted November 5, 2009 Ive only got two, but I really bought these for the rock as much as I did for the little ammos inside them. Very neato rocks. I found these at the Tucson show. RB Link to comment Share on other sites More sharing options...

I did hear one guy severely burnt inside his lungs.... Lance & Crinus.... Beautiful specimens.... RJB... I dont know if you have an ID for those but they are Eleganticeras elegans, from Whitby North Yorkshire....heres a link to the guy that usually preps and sells them, but looking through his stock he appears to be sold out....

Bill Posted November 5, 2009 Share Posted November 5, 2009 (edited) From Charmouth, England. Jurassic. Crucibiloceras? sp. I gave up on the prepping. Oxynoticeras sp. I hadn't noticed the space between the chambers was calcitic until the acid bath removed it. I haven't got round to id'ing these. Horton Clay Pit. Small Dole, England. Cretaceous, Gault Clay. These are quite small and unidentified. Edited November 5, 2009 by Bill KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out.

tracer Posted November 5, 2009 Share Posted November 5, 2009 having read up a bit now - pyrite dust is problematic in a number of ways besides acidification, including disease related to the iron side of things, and apparently explosion hazards too. inasmuch as FeS2 is dealt with in an industrial capacity, you can find a plethora of info online concerning its hazards, including MSDS sheets.

Terry Dactyll Posted November 5, 2009 Author Share Posted November 5, 2009 Tracer..... Good job I mentioned it.... pyrite crops up a lot in fossil collections, although I would imagine quite safe unless it is powederd down during prepping, when it becomes a inhalation problem.... Bill.... You second one is a Oxynoticeras... they look fantastic cut & polished... you probably think im taking the p--- now but im not. .. they have pyrite chamber walls and lime green calcitic infil.... I will start to hunt for one when Ive calmed down on collecting the big stuff.... Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
Bill Posted November 5, 2009 Share Posted November 5, 2009 (edited) Cheers Steve. No not at all, I have seen them cut/polished.

barefootgirl Posted November 5, 2009 Share Posted November 5, 2009 BFG, your'e only saying that to make me feel better after my Cut/polished posts. No, I meant what I said! In fact, after contemplating your side for a while I have decided not to cut open all my nautilods. Im going to leave the biggest as is and only have the medium sized one done. Im also going to stop giving them away!! You really do have some wonderful specimens Bill.

MikeD Posted November 9, 2009 Share Posted November 9, 2009 I bought this at a club auction a few years ago. Ammonite and imprint of same. From the personal collection of a former fossil curator at the Houston Museum of Natural History. It is put away at the moment, so I don't know the relevant info on it.
