    Sometimes you just get lucky. This geoduck (pronounced gooey-duck) was sitting with its mate in living state, filled with matrix, under a pile of landslide rubble at the water's edge. The exteriors of both shells were almost completely clean of matrix. Most other specimens were badly cracked in the matrix and would never have survived the fall.

    This shell was donated to the Delaware Museum of Natural History.
