Where: Ontario, Canada (43.2° N, 76.8° W: paleocoordinates 24.5° S, 48.0° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Rhuddanian (443.4 - 440.8 Ma)
• "Early Llandoverian (Rhuddanian, A to B1), Cabot Head Shale and Manitoulin Formation."
Environment/lithology: offshore; argillaceous limestone and green shale
•SEP: this is tough to assign to rigid carbonate/clastic settings. I have put it clastic setting because it is dominated by shales and is in the "clastic wedge" of the Silurian of the App. foreland basin
