C.85.3, southern Churchill Mountains (Cambrian of Antarctica)

Where: Antarctica (82.2° S, 160.3° W: paleocoordinates 1.3° S, 149.4° W)

• outcrop-level geographic resolution

When: Shackleton Limestone Formation (Byrd Group), Atdabanian (520.0 - 516.0 Ma)

• Scree, ice, and snow cover prevent measurements and thorough collecting for the stratigraphic collection.

•Was Atdabanian - Lenian, but restricted to Atdabanian in:

Damaske, G. Kleinschmidt, H. Miller & F. Tessensohn, eds.)

• formation-level stratigraphic resolution

Environment/lithology: marine; lithified limestone

Collection methods: The antarctic material was recovered during the Austral summer 1985-1986.
