Marco L Posted November 13, 2022 Share Posted November 13, 2022 Hello again, this time I found this fossil encased in rock or sediment in Big Brook. Unfortunately the rock is quite solid and I can't remove it. The fossil seems shell-like. Would appreciate a lot if someone could figure what it is. Also any ideas on how to remove the rock, would acid etching work? Link to comment Share on other sites More sharing options...
Lone Hunter Posted November 13, 2022 Share Posted November 13, 2022 Pictures aren't clear enough to tell much, last pic looks like shell fragments maybe. 1 Link to comment Share on other sites More sharing options...
erose Posted November 13, 2022 Share Posted November 13, 2022 I still have specimens like that. Hold onto them. Sooner or later you will find something similar and more diagnostic. 1 Link to comment Share on other sites More sharing options...

fifbrindacier Posted November 14, 2022 Share Posted November 14, 2022 (edited) I also see pieces of shell.

Marco L Posted November 14, 2022 Author Share Posted November 14, 2022 Is it identifiable of being from crustaceans or from shellfish? Link to comment Share on other sites More sharing options...

They're probably from an unidentifiable bivalve. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Marco L Posted November 14, 2022 Author Share Posted November 14, 2022 I see, should I try using acid to get rid of the rock? I don’t know if it is worth it. Thanks either way! Link to comment Share on other sites More sharing options...
fifbrindacier Posted November 14, 2022 Share Posted November 14, 2022 If you use acid you'll destroy the pieces of shell. I don't think this is worth trying to clean it. 1 1 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Carl Posted November 15, 2022 Share Posted November 15, 2022 I feel quite sure this is the claws of Mesostylus (the ghost shrimp) in matrix. I have found many very similar to this. 2 1 Link to comment Share on other sites More sharing options...
Marco L Posted November 15, 2022 Author Share Posted November 15, 2022 I was thinking it might be, there is a cavity in one of the shell pieces. I think water must have eroded it away, but it does look like the cavity inside the claw. 1 Link to comment Share on other sites More sharing options...
