Drake Bay Section, Prince of Wales Island, Unit 1 (Devonian to of Canada)

Where: Nunavut, Canada (73.5° N, 100.6° W: paleocoordinates 5.3° S, 24.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Drake Bay Formation, Eifelian to Eifelian (393.3 - 382.7 Ma)

• Unnamed formation, "probably partly correlative witht he Blue Fiord Formation" (which he assigns an age of Eifelian through Givetian). "Unit n" [from bottom] is my terminology, not Ormiston's. Unit is 3 feet thick. PJW: This should be Drake Bay formation.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; sandy limestone

• Reef development not observed in this section, but stromatoporoids occur at several horizons.

•SEP environmental call based on given info and regional context

• For section: "Thin-bedded, tan weathering limestones, argillaceous limestones, and shales are the predominant rock types." This unit: "Limestone: dark brown, finely crystalline, med. bedded, slightly sandy, slight petroliferous odur..."

Size class: macrofossils
