Triassic, Peace River Area (Triassic to of Canada)

Where: Alberta, Canada (56.2° N, 117.3° W: paleocoordinates 24.9° N, 31.9° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Toad/Grayling Formation, Griesbachian to Griesbachian (251.9 - 242.0 Ma)

Environment/lithology: marine; shale

• Non-carbonate nature
• Non-carbonate nature. In the east a sandy development indicates influx from this direction; over the shelf and the geosynclinal area silty shales and shaly siltstones are the common lithologies, ranging in color from light grey to black, often being calcareous or dolomitic. The sediments are platy and thin-bedded, and bear a certain resemblance to Kupferschiever lithology. In the upper beds coarse clastics came from a western source.

Size class: microfossils

Collection methods: core, chemical, mechanical,
