Where: Antarctica (64.2° S, 57.8° W: paleocoordinates 69.0° S, 52.4° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Whisky Bay Formation, Cenomanian (100.5 - 93.9 Ma)

• STRATIGRAPHIC RELATIONS: From the Whisky Bay Fm, which is regionally overlain by the Hidden Lake Fm (Coniacian), and overlies the Kotick Point Fm. AGE: Cenomanian, on the basis of stratigraphic position and macrofossil biostratigraphy. STRATIGRAPHIC POSITION: From beds in upper part of formation

• group of beds-level stratigraphic resolution
