• outcrop-level geographic resolution

When: Boston Cliffs Member (Choptank Formation), Serravallian (13.8 - 11.6 Ma)

• Camp Conoy; Middle and Upper Miocene (Serravallian), St Leonard and Boston Cliffs Members, Zones 18(?)-19, Choptank Fm. Samples taken from lower 1.6 m of section.

• member-level stratigraphic resolution

• Unconsolidated fossiliferous medium sand.

Size class: macrofossils

Collection methods: quarrying,

• Collected from individual specimens.
