Here is a beautiful fossil coral from the Miocene of Florida. This very large coral has been totally replaced by agate. The exterior of the specimen preserves the coral shape and structure. The inside of the specimen is filled with with botryoidal chalcedony or agate - and just covered with crystals! The many shapes and interesting formations make for a wonderful display. This is a fabulous example of ''Tampa Bay Coral'' that is becoming increasingly harder to obtain.
