Western Prince of Wales Island, Section 3, Unit 1, GSC loc. C26811 (Devonian of Canada)

Where: Nunavut, Canada (73.5° N, 100.0° W: paleocoordinates 2.2° S, 30.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• Unnamed formation.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; blue, argillaceous, silty lime mudstone

• Deposits in this region are of two general kinds: shallow-water stable carbonate platform (generally in the NW part of Arctic Archipelago) and deeper basinal facies (generally to the SE). This collection is in the former.

•SEP environmental call based on given info and regional context; possibly deep subtidal

• "thin- to medium-bedded lime-mudstone with common brachiopods, colonial corals, and common to abundant angular quartz silt" "thin-bedded, silty, argillaceous lime mudstone" "dark yellow-brown..silty-sandy"

Reposited in the GSC

• Smith gives specimen counts.
