Stratigraphy
Formation:Presumpscot
Stratigraphic resolution:group of beds
Stratigraphy comments: 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).
Lithology and environment
Primary lithology: unlithified "mixed carbonate-siliciclastic"
Includes fossils?Y
Lithology description: 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).
Environment:marine indet.
Glacial or sequence phase:transgressive
Geology comments: 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.
Taphonomy
Modes of preservation:body
Degree of concentration:concentrated
Size of fossils:macrofossils
Collection methods and comments
Collection methods:field collection,survey of museum collection
Reason for describing collection:general faunal/floral analysis
Collection method comments: COLLECTORS: Based on checklists of Dawson 1873, Clapp (1907), Bloom (1960). REPOSITORIES: Collections held in various museums, including YPM (Hendy, pers. comm.)
Taxonomic list comments:COVERAGE: Exhaustive for gastropoda, bivalvia, and polyplacophora. NOMENCLATURE: Not an authoratative publication, and somewhat antiquated. However, all occurrences include species-resolution assignments and list synonymies.
