Where: Netherlands (50.8° N, 6.0° E: paleocoordinates 43.3° N, 4.8° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Vijlen Member (Maastricht Formation), Early/Lower Maastrichtian (70.6 - 66.0 Ma)
• STRATIGRAPHIC RELATIONS: From the Vijlen Chalk of the Maastricht Fm, and overlies the Beutenaken Chalk of the Gulpen Fm. Where the Beutenaken Chalk is missing, the Vijlen Chalk rests unconformably on the Zeven Wegen Chalk. AGE: late Early Maastrichtian, on the basis of ammonite and belemnite biostratigraphy. STRATIGRAPHIC POSITION: Collection is a composite of the entire member.
• member-level stratigraphic resolution
Environment/lithology: lithified, phosphatic lime mudstone
Size class: macrofossils
Preservation: cast, mold/impression, replaced with phosphate
Collection methods: surface (in situ),
• COLLECTORS: Multople collectors. REPOSITORY: Institut Royal de Science Naturelles de Belgique (IRSNB), Naturhistorisch Museum, Maastricht (NHM), Museum für Naturkunde, Berlin (MNB)
