Atrypoidea bioherma Community, Upper Silurian, Arctic Canada (Silurian to of Canada)

Where: Nunavut, Canada (73.0° N, 93.0° W: paleocoordinates 0.2° S, 32.3° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Ludlow to Ludlow (427.4 - 419.2 Ma)

• Douro Formation on Somerset Island and Barlow Inlet Formation on Devon Island. Age is Upper Silurian, "Ludlovian and possibly Pridolian."

Environment/lithology: reef, buildup or bioherm; reef rocks

• "..brachiopod appears to have favored life in sheltered niches in bioherms...A BA 2 or shallow BA 3 assignment is reasonable."
• "Community formed almost entirely of A. bioherma is confined to bioherms. The beds between the bioherms contain A. foxi."
