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

They may be very well turritellids. They have a geological range from late Jurassic to recent. I'm leaning to more recent ones.

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?

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.

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.

This is easy (to say). Use the amino acid racemization method to date them. 

What and how do I did the acid test and what results am I looking for, thanks

I suggested it more as a topic that might be of interest than a working plan. I suspect it would have to be done in a laboratory.
