Jlark18 Posted December 9, 2023 Share Posted December 9, 2023 I found this fossil a few years ago along the Orange County, CA coastline. It was already partially smooth when found but I polished it a bit. Looks to be some shell fragments, possibly clams or oysters, mixed with silica and other local material.The colors are beautiful. Any thoughts on what the fossils may be? measures 7” x 5” x 3” and weighs roughly 5lb. Thank you! 3 Link to comment Share on other sites More sharing options...
Darktooth Posted December 9, 2023 Share Posted December 9, 2023 I have no idea what that is, but that is one heck of a beautiful rock! 5 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Lone Hunter Posted December 9, 2023 Share Posted December 9, 2023 I hope someone can explain what this is, I've never seen such an intriguing mosaic of color and pattern, like a peice of art gifted from the ocean 💦 Link to comment Share on other sites More sharing options...
FranzBernhard Posted December 9, 2023 Share Posted December 9, 2023 Very nice! Could be a jasper / chalcedony breccia. Don´t see any fossils. Franz Bernhard 2 6 Link to comment Share on other sites More sharing options...

Some of the white areas seem to be shell fragments, but that could be something else entirely. The most striking part of the rock is the yellow/tannish area with thin layers. Reminds me of oyster shell and flesh. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted December 9, 2023 Share Posted December 9, 2023 Oyster flesh does not fossilize and what appear to be shell fragments to you are mineral deposits and veins, probably quartz. No fossils for my eyes here. I agree with Franz on jasper/chalcedony breccia. 1 1 Greetings from the Lake of Constance.

I was not aware about the flesh unable to fossilize. 1 Link to comment Share on other sites More sharing options...
Baking Geologist Posted December 9, 2023 Share Posted December 9, 2023 Flesh needs a whole different environment to preserve than what would be present to create the breccia. It is a stunning piece though. 1 Link to comment Share on other sites More sharing options...
