Narrows Pond River (Holocene) (Holocene of Canada)

Also known as Newfoundland Loc. 2

Where: Newfoundland and Labrador, Canada (49.6° N, 57.9° W: paleocoordinates 49.6° N, 57.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• LITHOSTRATIGRAPHY: No lithostratigraphic unit reported in text. From emergent features along coast increasng in elevation to 250 ft above sea level. AGE: Late Wisconsin (Richards 1940). Coleman (1926) favored multiple glacial events, although MacClintock and Twenhofel (1940) and Richards (1940) indicate that deposits in Newfoundland are isochronous.

• group of beds-level stratigraphic resolution

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

• ENVIRONMENT: No specific environment provided in text for individual collection. Richards (1962) reports that collections were generally deposited in a cold, shallow sea.
• SPECIFIC LITHOLOGY: No detailed lithologic data reported in text. LITHIFICATION: Assumed to be unlithified given age and figured specimens in Richards (1962).

Size class: macrofossils

Collection methods: COLLECTORS: Collected by R.F. Flint, P. MacClintock, H. Johnson, A.K. Snelgrove, J. Wheeler, and others. Based on checklists of Richards (1940). REPOSITORIES: Collections held in various museums, possibly including the Academy of Natural Sciences, USNM, MCZ (Cambridge), and AMNH.
