Pds86 Posted March 5, 2018 Share Posted March 5, 2018 I'm not convinced that what I am looking at is in fact a fossil. I've checked several of my books on minerals and asked a few people and no one knows what these are. We were hiking some drainages in Central Colorado and found these near some copper deposits.

ynot Posted March 5, 2018 Share Posted March 5, 2018 Welcome to TFF! Your pictures are to blurry to be sure of anything other than - they are not fossils. Quote Link to post Share on other sites
Wrangellian Posted March 5, 2018 Share Posted March 5, 2018 Yep - too blurry. I like the sound of "gem-laden" but doesn't sound like a fossiliferous place. Quote Link to post Share on other sites
Rockwood Posted March 5, 2018 Share Posted March 5, 2018 These look pretty sedimentary to me. The second is a a bit septarian concretion like. Quote Link to post Share on other sites
abyssunder Posted March 5, 2018 Share Posted March 5, 2018 The green areas might be hydrated copper sulfate and hydrated copper carbonate. Maybe the specimens are copper ores. Quote Link to post Share on other sites
Ludwigia Posted March 5, 2018 Share Posted March 5, 2018 The photos are too out of focus to be able to make a proper judgement. Quote Link to post Share on other sites
