This specimen from the Oligocene Keasey formation is 5mm long. This shale is extremely hard, I had to use the 3 pound hammer to break it. The rock it was encased in was 8 x 9" and this was the only fossil I could find after breaking all in 1-3" pieces. Image is a Olympus Macro 60mm image on a Panasonic G9 camera using flash. Do you consider a fossil of this size a Micro fossil? I am going to leave it in the matrix because I've tried dental tools on this particular shale and it is just too hard. Need to do some further work on the ID with external shell features/geometry, but I think I am close.

Excavated from a block of submerged martrix deposited in the Chesapeake Bay by landslide. The common name, geoduck, is pronounced "gooey-duck." This specimen was donated to the Delaware Museum of Natural History.

This was excavated from a block of matrix collected from submerged landslide material in the Chesapeake Bay. The common name of the shell is pronounced "gooey-duck." The height listed is the diameter of the opening between valves on the posterior side, where the siphon extended.
