Folx-les-Caves, near Orp-le-Petit (Cretaceous of Belgium)

Where: Belgium (50.7° N, 4.9° E: paleocoordinates 41.3° N, 6.3° E)

When: Late/Upper Campanian (83.5 - 70.6 Ma)

• Since only a single sample was available for analysis, the biostratigraphical setting cannot be related to the first and last appearance datums of species, so that only the type of association is taken as an indication of the age of the parietal. The assemblage is typical of the early Late Campanian, zone CC 22 of Sissingh (1977), as based on the co-occurrence of Lithastrinus grilli, Aspidolithus parcus, Rheinhardtites anthophorus, Eiffellithus eximius and Uniplanarius sissinghii

Environment/lithology: marine; tuffaceous chalk

Size class: macrofossils

Collection methods: quarrying

• Museum of Natural History (Naturkundemuseum) of the Humboldt University (Berlin)
