Also known as Exshaw Formation at Mount Arete

Where: Alberta, Canada (52.4° N, 116.9° W)

• Paleocoordinates: 8.6° S, 53.3° W (Wright 2013)

• coordinate stated in text

• small collection-level geographic resolution

When: Palmatolepis expansa conodont zone, Lower Black Shale Member (Exshaw Formation), Late/Upper Famennian (364.7 - 360.7 Ma)

• Collection is a small lens.Undoubtedly Famennian brachiopods are said to co-occur with Mississippian-aspect conodonts. Raasch suggests that the Devonian fossils are part of a lag deposit.

• bed-level stratigraphic resolution

Environment/lithology: marine; black shale and pyritic siltstone

Size classes: macrofossils, mesofossils
