Unusual coloration. Typically these are red, sometimes with buff patches, but not usually all buff. The broken areas show the buff color to be a layer on the outside as there is red showing through the breakage. Collected from fallen cliff matrix in the bay containing index fossils of the Drum Cliff Member, Shattuck Zone 18. Donated to the Delaware Museum of Natural History

From the album: Calvert Cliffs
Can you believe I found this just sitting there, sticking out of a block of landslide material on the beach and wiggled it out with a screw driver? Never found even a suggestion of one before and this is only one of two I found in three days of carving through that block to discover the rest of its treasures. The other, sadly, is not in as good a shape, but still a treasure! Found at Matoaka Beach, St Leonard, Maryland. -

Due to the extremely fragile nature of this specimen, and the species in general, I was loathe to clear out any more of the matrix from the interior of the shell, so bits and pieces of other shells are present. The large central piece is the inner "cup," which attaches to the "saucer" at only a very small point in the tip. Collected from landslide material in the bay. Donated to the Delaware Museum of Natural History.
