Where: Nunavut, Canada (73.5° N, 100.5° W: paleocoordinates 2.1° S, 30.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• Age of faunas discussed at length in this paper. Author concludes they are correlative with Quadrithyris Zone of Nevada, and of Late Lochkovian age.

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; gray, argillaceous limestone

• "...well-preserved articulated specimens, suggesting that [shells] have been moved little, if any, from their habitat while living."

•SEP environmental call based on given info and regional context

• "The collections from Prince of Wales Island were taken from a slightly argillaceous grey limestone..."
