Sea Biscuit Fossils holden beach

these are from Holden Beach, NC. ALL imperfect, but they are 30 + million years old. in this lot there are either chunks missing or impartial. the 2 best ones have the hardened sand on them and would take some care to remove the hardened sand. please don't combine with other shell lots as it will exceed weight limits. okay to combine shipping with a clothing item perhaps. left a picture up of brief description.
