Art,

Then how do you explain the Noetia ponderosa that I found at a Boy Scout
camp in western Pennsylvania? If it is dead, it might come from the
location where it is found or it may have been transported there by other
means.Beach replenishment? Someone seeding the beach in a tourist area?
You should see some of the Indo-Pacific shells that people have given to
me from their beachcombing walks in Florida!

I always list items as:
1) Live collected
2) Dead collected, live specimens present
3) Dead collected

This way I have a rough idea about the validity of the locality data.

Regards,
Charlie

> O.K., Here's one thought! Unless they are very light and/or pelagic, dead shells would have to come from pretty close. Weight would cause them to be pretty close to the bottom. Storms could send unusual material up on beaches. But I betcha most of what you find dead on a beach would be live there at some time.
