    • Barnacles are very abundant at some exposures in North Carolina. So at these places( and this was one of them) it takes a unique specimen for me to pick it up. This one caught my eye. Rather large and complete, plus has a natural display "seat". C. concavus is kind of a catch all for many barnacles that are found in the Pliocene.
