Where: Nunavut, Canada (73.6° N, 94.8° W: paleocoordinates 0.0° N, 0.0° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Hunting Formation, Stenian (1200.0 - 1000.0 Ma)
• From the lower part of the Hunting Formation, an estimated 100 m above the base. The Hunting Formation is thought to be correlative with the "Society Cliffs" (Angmaat/Nanisivik) Formations of the Bylot Basin, which are dated at c. 1047 Ma from Re-Os dating of the underlying Arctic Bay Formation (1.048 +/- 0.012 Ga) and the overlying Victor Bay Formation (1.046 +/- 0.016 Ga).
• bed-level stratigraphic resolution
Environment/lithology: peritidal; lithified, stromatolitic, cherty/siliceous dolomite
Size class: microfossils
Preservation: permineralized, original carbon, replaced with silica
Collection methods: peel or thin section
• Repository: Harvard University Paleobotany Collection
