daves64 Posted February 11 Share Posted February 11 Septarian concretion from the look of it. 3 Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...

Mike Vick Posted February 11 Author Share Posted February 11 I'm curious about what the nucleus is? There's a white shell like layer surrounding the nucleus, followed by three separate outer crystalline layers. Link to comment Share on other sites More sharing options...

DPS Ammonite Posted February 11 Share Posted February 11 I bet that most of it is a carbonate like calcite or aragonite. See if it fizzes in acid. 1 My goal is to leave no stone or fossil unturned.

Rockwood Posted February 11 Share Posted February 11 Yes. Septarian concretion. Link to comment Share on other sites More sharing options...
FranzBernhard Posted February 11 Share Posted February 11 Difficult, to say the least! The two grey blobs in the center could be inner molds of a half open bivalve, with the white stuff around it being some shell remnants. Are there any bivalves of similar shape and size in that formation? Franz Bernhard 2 Link to comment Share on other sites More sharing options...

I think this tends to contradict the shell idea in favor of multiple cycles in its formation precipitating different minerals. Link to comment Share on other sites More sharing options...

FossilDAWG Posted February 11 Share Posted February 11 The material surrounding the two "blobs" looks like a section through an inoceramid bivalve to me. I think this is a bivalve in a septarian concretion. As Kane said, better locality data would be helpful. Canada is a very large place, and includes fossils of every age from Ediacarian to latest Pleistocene/Holocene. Don 2 Link to comment Share on other sites More sharing options...
Mike Vick Posted February 13 Author Share Posted February 13 I found it on a property we purchased in Castlegar BC amongst a bunch of other rocks and stones. I'm told that the previous owner was a geologist and a stone cutter. Other than that,I have no further information on the exact location unfortunately 😕 1 Link to comment Share on other sites More sharing options...
Lone Hunter Posted February 13 Share Posted February 13 A geologist huh, that really expands the horizon from where it could have originated. It looks like a bivalve with calcite in a concretion in a septarian concretion to me. Link to comment Share on other sites More sharing options...

There's a white shell like layer surrounding the nucleus, followed by three separate outer crystalline layers. I would agree with the assessment that the nucleus is the steinkern of both shells of some type of bivalve. The white substances and crystalline layers are remnants of the original shell in my opinion. Greetings from the Lake of Constance.
