Guest N.AL.hunter Posted October 20, 2010 Share Posted October 20, 2010 (edited) We all have seen calcified (including limestone), silicified, agatized, pyrtized, opalized, carbonized, amberized (OK, not a real word) and so on... So what unusual preservation do you have in your collection? I ask this cause online I found a rolled trilobite that appeared to be preserved in malachite. My coon Creek fossils are un-altered shell material and they are from the Cretaceous (available in my Gallery)! Any weird items out there?

jpc Posted October 21, 2010 Share Posted October 21, 2010 Years ago while working for the U of wyoming, I ofund a Paleocene leaf localtiy that had not the impressions or carbon imprints of leaves, but real three dimensional leaves that blew away as you peeled the rock open. I still have. I'll try to post pix in the next few days. Link to comment Share on other sites More sharing options...

CreekCrawler Posted October 21, 2010 Share Posted October 21, 2010 I seem to remember back when I joined this site that there were some truly amazing Opalized bacculites that I think originated from Australia. Most amazing replacement I have ever seen.Anyone remember those pictures ???? Link to comment Share on other sites More sharing options...

bear-dog Posted October 21, 2010 Share Posted October 21, 2010 (edited) The most difficult strange preservation is a couple of mummified pieces from the Caloosa Shell Pit.Out of roughly 2 pick-up truck loads of trunks and tree limbs,I managed to preserve a piece of wood about the size of your thumb and 2 pine cones.As the wood dries it turns to dust,so your preservation tequnique has to begin with a wet specimen.Which still is iffy at best.

frozen_turkey Posted October 21, 2010 Share Posted October 21, 2010 here is mine. Its a gastropod with most of its shell preserved as calcite. Its from the middle devonian period (ceder valley group(?)) and was found near robins, IA. This one of the rarest fossils i have in my colection and its the only one ive ever found. And what realy surprizes me is the fact that fine details near the opening were pereserved and that the calcite isn't crushed. Also you can see my sad prep atemped. I was origenaly going to try to prep it, but i had second thoughts. I then disided that it would be best to hae a pro do it or wait till i get better equipment. O and id love to get my fingers on one of those opal fossils. -frozen Link to comment Share on other sites More sharing options...

JimB88 Posted October 22, 2010 Share Posted October 22, 2010 I was just at the KGMS show and some vendors had those ammonites where only the sutures are preserved (in pyrite)the rest is gone, so they look like hollow latticework. I should have bought one. Link to comment Share on other sites More sharing options...

jpc Posted October 22, 2010 Share Posted October 22, 2010 (edited) Well, dang... how come we can't all see the pix? I can count the fossil I have actually paid for on two hands, but I just bought a Lightning Ridge belemnite at the Denver show a month or so ago. I've loved opal since I first heard abot it in elementary school. When I was in Oz I went to Lightning Ridge and actually found a few pieces of opal in the scrap piles. And there is an opalized plesiosaur skeleton in one of the rock shops. But that shop is closed on Wednesdays and I was there only on Wednesday. Had to leave early the next morning to hitchhike into Sydney for a plane ride out of Oz. Meanwhile here are a few photos of my scrap of Paleocene leaf. A genuine 50 million yr old leaf. One pictur eis of it up against thelight in the loiving room, the other is of it not backlit. Totally amazing preservation. We took a paleobotanist there later and I htinkshedid good things with the few pieces we were able to find. Edited October 22, 2010 by jpc Link to comment Share on other sites More sharing options...

pleecan Posted October 22, 2010 Share Posted October 22, 2010 (edited) In the Bertie Lagerstatte... eurypterids preserved in the Bertie Formation is so finely preserved that sometimes as you split the rock to exposed the eurypterid... the chitin from the little animal peels off like brown onion skin.... really amazing. http://palaios.geoscienceworld.org/cgi/content/abstract/22/4/439 Edited October 28, 2010 by pleecan Link to comment Share on other sites More sharing options...
Blastoid Posted October 22, 2010 Share Posted October 22, 2010 I have a gastropod replaced by pink rhodochrosite. Fossils with dark green vivianite crystal clusters inside are cool too, as are the Florida bivalves filled with clear golden calcite crystals.

Auspex Posted October 24, 2010 Share Posted October 24, 2010 ...here are a few photos of my scrap of Paleocene leaf. A genuine 50 million yr old leaf... Totally amazing preservation. We took a paleobotanist there later and I htinkshedid good things with the few pieces we were able to find. I wonder whether any bits of DNA are lurking in those leaves? Some was successfully extracted from leaves from the Miocene Clarkia, Idaho beds.
