Kaskattama No. 1 Well, 2098 ft. level (Silurian of Canada)

Also known as Sogepet - Aquitaine - Kaskattama - Province No. 1

Where: Manitoba, Canada (57.2° N, 90.2° W: paleocoordinates 8.4° S, 46.6° W)

• small collection-level geographic resolution

When: Lower Carbonate Unit Member, Llandovery (443.4 - 433.4 Ma)

• "Although the assemblage is Silurian, it cannot be definitely assigned to Series... An Early Silurian date is tentatively accepted here because of Virgiana decussata." [Therefore I have entered Llandovery as Epoch.]

The faunal assemblage has been dubbed "Port Nelson assemblage" by the authors but they caution that it is not certain that the fossils are characteristic of the Port Nelson Formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, concretionary, dolomitic, brown, gray grainstone and lime mudstone

• "The carbonates are brown and grey-brown and develop a rhythmic sequence between a fine-grained bioclastic calcarenite with a nodular to well-bedded aspect, alternating with a more comm[?] cryptocrystalline, finely fragmental phase. [Dolomite] becomes minor above 1800'."
