Where: British Columbia, Canada (55.5° N, 122.7° W)

• Paleocoordinates: 32.6° N, 41.1° W (Wright 2013)

When: Pardonet Formation (Schooler Creek Group), Norian (228.0 - 208.5 Ma)

Environment/lithology: open shallow subtidal; lithified, dolomitic, pyritic, black, gray, argillaceous limestone and calcareous siltstone

The lower beds are somewhat thinner bedded and more arenaceous than the upper ones.

Size classes: macrofossils, mesofossils
