Where: Antarctica (64.2° S, 57.8° W: paleocoordinates 67.5° S, 48.4° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Kotick Point Formation, Albian (113.0 - 100.5 Ma)

• STRATIGRAPHIC RELATIONS: From the Kotick Point Fm, which is regionally overlain by the Whisky Bay Fm (Albian-Coniacian). AGE: Albian, on the basis of ammonite biostratigraphy; here placed in the Albian on the basis of stratigraphic position. STRATIGRAPHIC POSITION: From beds in upper part of the section.
