Pardonet 1, upper Peace River (Triassic of Canada)

Where: British Columbia, Canada (56.1° N, 123.0° W: paleocoordinates 27.5° N, 42.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pardonet Formation, Carnian (237.0 - 228.0 Ma)

• At the base are 500 feet of "Grey Beds" consisting of limestone rocks described in the lithology section. The overlying 1850 feet are largely concealed, indicating more shaly beds, characteristic of the Pardonent Formation. The probable age is late-middle or early-late Carnian.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; limestone

• light-grey limestones and magnesian limestones, partly arenaceous and crinoidal limestone, calcareous partly argillaceous fine sandstone, with a somewhat restricted shallow water benthonic fauna of brachiopods and pelecypods

Size class: macrofossils

Collection methods: Repository: Department of Geology, McMaster University, Hamilton, Ontario
