Where: Greenland (72.9° N, 25.1° W: paleocoordinates 0.0° N, 0.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Andrée Land Group, Tonian (1000.0 - 850.0 Ma)

• From the Limestone-Dolomite "Series", Eleonore Bay Group. Later assigned to the Andrée Land Group by Sønderholm & Tirsgaard (1993). The Andrée Land Group underlies the Sturtian-equivalent glacial episode in Greenland (Klaebe et al., 2018), which makes it Tonian in age using the current placement of the base-Cryogenian at 720 Ma, the onset of the Sturtian glacial.

• bed-level stratigraphic resolution

Environment/lithology: peritidal; lithified, stromatolitic, cherty/siliceous limestone

Size class: microfossils

Preservation: permineralized, original carbon, replaced with silica

Collection methods: peel or thin section
