Hopedale (Holocene) (Holocene of Canada)

Also known as Labrador Loc. 5

Where: Newfoundland and Labrador, Canada (55.4° N, 60.2° W: paleocoordinates 55.5° N, 60.2° 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 elevated beaches along coast in elevation to 265 ft above sea level, even up to 390 ft (Packard 1866, Daly 1902). AGE: Late Wisconsin (Richards 1940).

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; unlithified 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: Based on checklists of Packard (1865) and Dawson (1873). REPOSITORIES: Collections held in various museums, possibly including the Academy of Natural Sciences, USNM, MCZ (Cambridge), and AMNH.
