Craie de Ciply, Mons Basin (Cretaceous of Belgium)

Where: Belgium (50.4° N, 3.9° E: paleocoordinates 43.0° N, 3.0° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Craie de Ciply Formation, Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Craie de Ciply, which unconformably overlies the Craie de Spiennes (Late Campanian), and is unconformably overlain by the Tuffeau de Saint-Symphorien (Late Maastrichtian). AGE: Early Maastrichtian, on the basis of ammonite and belemnite biostratigraphy. STRATIGRAPHIC POSITION: Collection is a composite of the entire formation.

• formation-level stratigraphic resolution

Environment/lithology: lithified, phosphatic, brown, gray, calcareous, cherty/siliceous sandstone

• ENVIRONMENT: Shallow marine carbonate setting.
• SPECIFIC LITHOLOGY: Gray to brownish calcarenite consisting of many phosphatic grains in a chalky matrix and generally with flint bands. LITHIFICATION: Lithified on the basis of facies description.

Size class: macrofossils

Preservation: cast, mold/impression

Collection methods: surface (in situ),

• COLLECTORS: Multpple collectors, but probably including W.J. Kennedy. REPOSITORY: Institut Royal de Science Naturelles de Belgique (IRSNB), Naturhistorisch Museum.
