Scallop Fossil Shells

[Lane7420]

These are just a few of the best fossil scallops I’ve found over the years. They were found in the Gulf of Mexico Bay Area in Carrabelle, Florida. I have searched the web for answers but It becomes more confusing the more I read. I’m wondering if you can tell me about these scallops, how they are fossilized and how old they are? 
Thank you,

Nice scallops.  I'm a big fan of oysters and scallops as well.  Again, referring to a geological map of FL  (see https://search.yahoo.com/search?p=geological+map+of+florida&fr=yfp-t-s&fp=1&toggle=1&cop=mss&ei=UTF-8  says that Carrabelle, Florida is also in the Pleistocene period.  So again, 10,000 yr ago for age.

I would have liked to have checked out that link, but I don't agree with being forced to share my cookies. Sorry.
