Where: Sweden (55.4° N, 13.8° E: paleocoordinates 45.4° N, 13.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Santonian (86.3 - 83.6 Ma)

• STRATIGRAPHIC RELATIONS: From an unnamed lithostratigraphic unit. AGE: Santonian, on the basis of foraminiferal and ammonite biostratigraphy, and stratigraphic position. STRATIGRAPHIC POSITION: From 481.26-481.35 m in core.
