Where: Calvert County, Maryland (38.5° N, 76.5° W: paleocoordinates 38.7° N, 73.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Calvert Beach Member (Calvert Formation), Langhian (16.0 - 13.7 Ma)

• Ward & Andrews (2008) state that the Calvert Beach Member should not be used and that Shattuck's zone 16 is not viable. It is not clear whether this collection belongs to the lower beds 14-16, or to bed 17, but it is more likely that it belongs to the lower beds and is thus Langhian.
