Also known as Canadian Arctic Archipelago

Where: Nunavut, Canada (68.9° N, 114.3° W: paleocoordinates 0.9° S, 55.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Tremadocian (485.4 - 477.7 Ma)

• Flower (1964 pp. 74, 75) says that the Cephalopods from the Read and Sutton islands are of Canadian (Lower Ordovician) age whereas Miller & Youngquist (1947) say that the rocks on both the islands are Late Ordovician in age.

• formation-level stratigraphic resolution

Environment/lithology: gray dolomite

Size class: macrofossils

Preservation: cast, recrystallized, original calcite, replaced with dolomite, replaced with silica

Reposited in the YPM

Collection methods: surface (float), surface (in situ),

• "The majority of the specimens were found in situ, but some of them were collected from loose boulders. A few were picked up by Eskimos." is a general statement and does not inevitably apply to all of Miller and Youngquist's (1947) collecting localities.
