Denis Arcand Posted May 22, 2023 Share Posted May 22, 2023 I found a unique fossil in the Ordovician formation, but I'm unsure if it's coral or something else. Any thoughts or suggestions?

Denis Arcand Posted May 22, 2023 Author Share Posted May 22, 2023 I'm hoping for coral, but it might just be a block of cement with spot on it One fossil a day will keep you happy all day. Welcome to the FOSSIL ART Link to comment Share on other sites More sharing options...
FranzBernhard Posted May 22, 2023 Share Posted May 22, 2023 Does not look like cement. The bright spots seem to be 3D? Do you see any microstructures? Franz Bernhard 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 22, 2023 Share Posted May 22, 2023 I'm thinking it is some kind of mineral staining. I don't think this is a fossil. 1 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

The circular spots are just a bit 3d almost not perceptibable. I tried a dremel on it, but it almost done nothing the rock is to hard, the dark area is a little bit softer but although also very hard. I was able to even out a small part with an electric belt sander. I can say It is not surface stainning it seams to be more deep in the rock. Here a photo from before sanding and after sanding. 1 One fossil a day will keep you happy all day. Welcome to the FOSSIL ART Link to comment Share on other sites More sharing options...
Kane Posted May 22, 2023 Share Posted May 22, 2023 I'm with an expert here in Quebec. We agree this is mineralization with something to do with deposition and maybe leeching. 2 1 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

We agree this is mineralization with something to do with deposition and maybe leeching. Thank you, @Kane, for your input. I completely agree, there are no discernible details that suggest it could be coral. Upon closer examination with a magnifying lens, it appears to have a distinct granular structure. I submitted it for identification because it was out of the ordinary, It might be something that was deposit there a long time ago by glacier or some other geologic process. I plan to cut it in half and polish it, as this might reveal an intriguing pattern or motif. 1 One fossil a day will keep you happy all day.

doushantuo Posted May 23, 2023 Share Posted May 23, 2023 (edited) iron rich orbicular olivine gabbronorite ,perhaps. If so,not particularly biogenic any red coloration may be enhanced by fungal enzymatic reduction of iron Edited May 23, 2023 by doushantuo 1 Link to comment Share on other sites More sharing options...
