Zeven Wegen Chalk, Gulpen Fm (Cretaceous of Netherlands)

Where: Netherlands (50.8° N, 6.0° E: paleocoordinates 41.4° N, 7.2° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Zeven Wegen Chalk Member (Gulpen Formation), Late/Upper Campanian (83.5 - 70.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Zeven wegen Chalk, the lowermost member of the Gulpen Fm, and is overlain by the Beutenaken Chalk. The Terstraeten Sand of the upper Vaals Formation underlies the unit. AGE: Latest Campanian, on the basis of ammonite and belemnite biostratigraphy. STRATIGRAPHIC POSITION: Collection is a composite of the entire member.

• member-level stratigraphic resolution

• ENVIRONMENT: Shallow marine carbonate setting.
• SPECIFIC LITHOLOGY: No specific lithological data reported in text. Probably chalk. LITHIFICATION: Lithified on the basis of figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression
