Daniel's Harbor boulders (Ordovician of Canada)

Where: Newfoundland and Labrador, Canada (50.2° N, 57.6° W: paleocoordinates 28.6° S, 42.7° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Table Cove Formation (Table Head Group), Whiterockian (470.0 - 457.3 Ma)

• Formation assignment based on faunal assemblage ("Middle Table Head" of Whittington and Kindle 1963 = Table Cove Formation of Klappa et al 1980).

Environment/lithology: slope; gray limestone

• Environment based on interpretation of Table Cove Formation by Stenzel et al 1990

• "The conglomerate...includes many flat angular slabs of dark-gray limestone and some large blocks of interbedded, thin, dark limestone and shale." Slabs are fossiliferous (trilobites, graptolites).

Size class: macrofossils
