Kennebunk, York Co. - Presumpscot Fm (Pleistocene) (Pleistocene of the United States)

Also known as Maine Loc. 13

Where: York County, Maine (43.3° N, 70.5° W: paleocoordinates 43.3° N, 70.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Presumpscot Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• LITHOSTRATIGRAPHY: No lithostratigraphic unit reported in text. Bloom (1960) assigned the name "Presumpscot Fm" to the sheet of emerged marine sediments that blankets the coastal region of southwestern Maine. AGE: Wisconsin (Levitt and Perkins, 1935), Late Pleistocene (Bloom 1960), Pleistocene (Richards 1962).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; unlithified mixed carbonate-siliciclastic sediments

• ENVIRONMENT: No specific environment provided in text for individual collection. Richards (1962) reports that collections were generally deposited in shallow marine settings, during sea level transgressions.
• SPECIFIC LITHOLOGY: No detailed lithologic data reported in text. Text talks of shell beds for Late Pleistocene deposits in Maine described by Packard (1865), Clapp (1907), and Levitt and Perkins (1935) LITHIFICATION: Assumed to be unlithified given age and figured specimens in Richards (1962).

Size class: macrofossils

Collection methods: COLLECTORS: Based on checklists of Dawson 1873, Clapp (1907), Bloom (1960). REPOSITORIES: Collections held in various museums, including YPM (Hendy, pers. comm.)
