Where: Northwest Territories, Canada (62.4° N, 127.0° W: paleocoordinates 6.2° N, 50.8° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Delorme Formation, Wenlock (433.4 - 427.4 Ma)
• Zonation based on conodonts present in AV sections 1, 2, and 4. (AV 3 and DR sections correlated with these on basis of trilobite faunal assemblages. I'm assuming AV5 can be correlated as well.) See PBDB ref. 7215. This fauna is between j (early Wenlock) and k (upper Wenlock/lower Ludlow).
• group of beds-level stratigraphic resolution
Environment/lithology: slope; argillaceous limestone and shale
•SEP environmental call based primarily on PBDB ref. 7215.
Preservation: replaced with silica
