Where: Belgium (50.8° N, 5.7° E: paleocoordinates 43.3° N, 4.6° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Vijlen Member (Maastricht Formation), Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• bed-level stratigraphic resolution
Environment/lithology: lithified, phosphatic lime mudstone
Size class: macrofossils
