Dear Tino,
One dating method that has worked well with large gastropods is aspartic acid racemization. The late Glenn Goodfriend did a study of the Caribbean slit shell Entemnotrochus adansoniana using this method, and got very good results. See for example:

or

Hi Everybody
I would like to get recommendations concerning an analyisis that I would like to do for my project.
This involves dating of conch shells (Stronbus gigas). Conchs that have been harvested.
I was thinking if there was a method of carbon dating or any other method that anybody might know I could use to age these shells and to determine the time when they were harvested.
