San-Cap Shell Club assists with quarry dig
In early December, Sanibel-Captiva Shell Club Field Trip Chair Susi Butler organized a quarry dig with other members to assist University of Florida scientists in their field research and to collect shell fossils, including an amazing find of a fossil junonia. Roger Portell, Carmi Thompson and a few others from the UF/Natural History Museum conducted their research work on shell fossils at a quarry south of Arcadia that is closed to visitors. Over the first three days, they sampled various layers in the walls of the quarry, up to 17-feet tall. Shell fossils that have been buried for 2 million to 3 million years were visible. Club members were allowed to collect shell fossils at the end of each day, going home with several interesting ones. A few found shark eye shells with their operculums tucked inside, was well as large whelks, scallops, nutmegs and a turbinella.
