Scottnokes2015 Posted January 10, 2019 Share Posted January 10, 2019 Hi guys. A member of my club have these away. Can you tell me what they are and if they are fossils our modern day Shell's from the beach. I have no idea were they came from. Thank you Link to comment Share on other sites More sharing options...
abyssunder Posted January 10, 2019 Share Posted January 10, 2019 They may be very well turritellids. They have a geological range from late Jurassic to recent. I'm leaning to more recent ones.

caldigger Posted January 10, 2019 Share Posted January 10, 2019 By the looks of them I would guess no earlier than Pleistocene. If the bloke is in your club, why dont you just ask him for specifics? Link to comment Share on other sites More sharing options...

HoppeHunting Posted January 10, 2019 Share Posted January 10, 2019 I'd say more modern. Most of the older (i.e. Miocene, Paleocene) spiral gastropod shells that I have all have a smoother outer surface, while the ones pictured appear to have many striations/rings. This is only a guess; I am no expert on gastropods. The Hunt for the Hemipristine continues! ~Hoppe hunting!~ Link to comment Share on other sites More sharing options...
Ludwigia Posted January 10, 2019 Share Posted January 10, 2019 Pleistocene is not modern. They look fossiliferous to me. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Rockwood Posted January 10, 2019 Share Posted January 10, 2019 This is easy (to say). Use the amino acid racemization method to date them. Link to comment Share on other sites More sharing options...
Plax Posted January 10, 2019 Share Posted January 10, 2019 scale? They look a bit like Turritella mortoni from the Paleocene of Maryland but without provenance they could be any age or formation. I agree that they look like fossils. Link to comment Share on other sites More sharing options...

What and how do I did the acid test and what results am I looking for, thanks Link to comment Share on other sites More sharing options...

I suspect it would have to be done in a laboratory. wikipedia Here is a brief of the concept. 1 Link to comment Share on other sites More sharing options...
