Large Fossil Barnacles Lot of 3 Southwest Florida

Description

This lot of 3 barnacle fossils is from my personal collection.  Collected by me from an excavation in Southwest Florida from a depth from around 20 feet or so about 15 years ago.  I also collected many different fossils from a variety of land and sea creatures in this same location.
Large barnacle is about 5" x 5" and 3" tall
Medium is about 3" x 2 3/4" x 1 3/4 tall
Small is about 2 1/2" x 2 1/2" x 1 3/4 tall
Thanks for looking!
