DPS Ammonite Posted January 11, 2020 Share Posted January 11, 2020 I saw an interesting modern “fossil”, a copper pseudomorph after a scorpion owned Flagg Mineral Foundation member, Bill Yedowitz. It will be featured in an upcoming special edition of Rock and Gem Magazine. Native copper and copper minerals sometimes replace and coat organic matter left in mines. I have seen pictures of copper replacing mining timbers and wood tool handles. I have heard that a crushed prehistoric Native America was found in an ancient mine in the SW US. Because the bones were replaced with malachite, it was named the Malachite Man and reburied. Another version of the story might be found here: https://en.m.wikipedia.org/wiki/Moab_Man Although too young to be a fossil yet, older fossils might be found that answer an earlier TFF post about whether or not native copper could be a fossil. @Herb @Auspex 10 My goal is to leave no stone or fossil unturned.

Ludwigia Posted January 11, 2020 Share Posted January 11, 2020 Amazing! How old do they figure this is? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

RuMert Posted January 11, 2020 Share Posted January 11, 2020 Moscow Fersman museum has something similar: an atacamite (also a copper-based mineral) pseudomorph after a mouse. Hard to believe such things 9 My sites & reports Link to comment Share on other sites More sharing options...
FranzBernhard Posted January 11, 2020 Share Posted January 11, 2020 Mouse could be ok, scorpion is not ok! This is artificially made: Electroplating of copper onto scorpion coated with some conductive material. Botryoidal shape and accumulation of copper at the tips of the specimen is typical for electroplating such things! Pseudomorph is also not correct, seems to be an epimorph. Age is ok, tough . Maybe even the site is "ok": Just look for a pool with copper-bearing water at/in an old mine, take a conductively coated, dead scorpion and wire it to e.g. a car battery as cathode; use a lead sheet as anode. Wait some time, then go harvesting... Franz Bernhard 6 Link to comment Share on other sites More sharing options...
