Comments
This was carved carefully from a block of matrix that fell out of the cliffs into the bay. Of the dozens that I found, this was one of the few that did not completely fall apart what it was separated from the surrounding sand. Though thicker than many shells in the same chunk of sand, they are extremely soft in this location and incredibly fragile.
Donated to the Delaware Museum of Natural History.
