Where: Ontario, Canada (44.8° N, 81.2° W: paleocoordinates 24.8° S, 45.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Eramosa Formation, Wenlock (433.4 - 427.4 Ma)

• Early Wenlock (433-430 Ma)

• group of beds-level stratigraphic resolution

• Interpreted by Armstrong (1993) as the lagoonal marine facies of the more massive, reefal Guelph Formation.
• Exceptional preservation is confined to an ~7–9-m-thick alternating dolostone, limestone, and bituminous shale sequence, the Interbedded Unit of Armstrong and Meadows (1988), recognized only on the Bruce Peninsula.

Size class: macrofossils
