New Members Beeba Posted August 3 New Members Share Posted August 3 I think this is a crystalized bone fossil, but I'm new to this. Unfortunately I can't know for sure where it came from, I bought a box of mixed rocks, petrified wood and what look like fossils in an auction in Butte County Northern California. Any ideas would help. Thank you all very much. Link to comment Share on other sites More sharing options...
Andreik Posted August 3 Share Posted August 3 I don't see any bone, it looks like calcite. 3 Link to comment Share on other sites More sharing options...
Rockwood Posted August 3 Share Posted August 3 I think quartz is more likely. It's not bone though. 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 3 Share Posted August 3 Definitely geologic in origin, not biologic. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

FranzBernhard Posted August 3 Share Posted August 3 Looks like boxwork structure. Boxwork - Wikipedia Franz Bernhard 1 Link to comment Share on other sites More sharing options...
ynot Posted August 3 Share Posted August 3 This is a section of a mineralized quartz vein, with a lot of iron oxide staining. Very common throughout the Sierra Nevada mountains. Often associated with gold, so look close. 2 Link to comment Share on other sites More sharing options...
