Where: Seymour Island, Antarctica (64.3° S, 56.8° W: paleocoordinates 63.1° S, 66.7° W)
• small collection-level geographic resolution
When: Lopez de Bertodano Formation, Danian (66.0 - 61.6 Ma)
• This is restricted to Unit 10, of the 10 units into which the Lopez de Bertodano FM was divided, and it contains the K-T boundary, though it is ill-defined. This collection is only for Unit 10 taxa collected ABOVE the "K/T transition interval", and so is clearly Danian in age.
• bed-level stratigraphic resolution
Environment/lithology: offshore; poorly lithified, bioturbated, glauconitic, silty sandstone and siltstone
Collection methods: bulk,
• All macrofossils were collected
