Kane Posted March 4, 2017 Share Posted March 4, 2017 Looks very much like an eroded bivalve. A nice piece. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
DesireeMae Posted March 4, 2017 Author Share Posted March 4, 2017 Thank you! do you think it's freshwater? Wonder what era it would be from? Link to comment Share on other sites More sharing options...
Kane Posted March 4, 2017 Share Posted March 4, 2017 Could you tell me where in Northern Idaho? ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Kane Posted March 4, 2017 Share Posted March 4, 2017 Hm... So far I've been able to identify the age as possibly Cretaceous, but I'll need to do some more digging. EDIT: I seem to be stuck. The fluting on this is really throwing me off. I don't think it could be Exogyra sp. since the hinge doesn't look quite right, nor do I think it could be Venericardia sp. since the shape is not quite right (and that would place it in the Eocene). I seem to be coming up empty-handed at the moment for any good sources on Idaho bivalve fossils until I can get to campus. Let's hand this off to the bivalve experts for now! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Kane Posted March 4, 2017 Share Posted March 4, 2017 And perhaps for our bivalve connoisseurs, if you could possibly supply a picture of the hinge / umbo straight on? That can sometimes help for ID. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
fossilcrazy Posted March 5, 2017 Share Posted March 5, 2017 Perhaps a Cretaceous Neithea cockle. Link to comment Share on other sites More sharing options...
