I have found a few of these over the years, but it was only recently that I looked closely enough to see that they were not broken bits of the fossil barnacles clusters that litter the beach. The shape, color and texture are actually quite different from the barnacles at this location. This one was excavated from a chunk of landslide material that also contained index fossils of the Drum Cliff Member.

From the album: Calvert Cliffs
Collected loose on the beach in St. Leonard, Maryland middle Miocene Choptank Formation Drum Cliff Member Chesapectin nefrens is an index fossil for the Drum Cliff Member of the Choptank Formation, meaning that whatever chunk of matrix one may find fallen out of the cliffs, the precise layer is known so that other fossils in the same block can be identified. These are a very common find at St. Leonard and other places, but I particularly liked the coloration on this one!© Heather JM Siple 2018

Excavated from matrix in the Chesapeake Bay, about 10 feet off of the beach at low tide. View is external on both valves, but hard outer coating has been lost to decay. Valves are pearlescent.
-
Excavated from landslide material approximately 1/2 mile nw of Matoaka beach access. Found 4 that week. Two survived excavation. This is the only one discovered intact.

This specimen was made incredibly soft by the surrounding matrix. The thin veneer of glossy coloration has worn away, but can be seen on this specimen, which came from the same 2 ft x 1ft x 1ft block of matrix that fell out of the cliff into the bay. Half a dozen of these were collected from that and one other small, adjacent block that day, along with more than two dozen other species. Layer originally designated Shattuck Zone 18. Donated to the Delaware Museum of Natural History.
