Quadrithyris Zone Brachiopods, Bathurst Is., Section 33, GSC loc. 67041 (Devonian of Canada)

Where: Nunavut, Canada (76.0° N, 98.0° W: paleocoordinates 2.1° S, 26.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Stuart Bay Formation, 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: open shallow subtidal; green, yellow limestone

• "well-preserved, articulated specimens" "The collection may well represent a faunule that existed in a sheltered area associated with a biostrome or small reef."

•SEP: environmental call based on given description but there is probably lots of fine and coarse siliciclastic interbedded with the ls. from which these fossils were derived. it is therefore probably better classified as a siliciclastic environment

• "greenish tan limestone"
