El Koubbat Kou. 175 (Cretaceous of Morocco)

Where: Morocco (33.1° N, 5.3° W: paleocoordinates 24.6° N, 5.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Irbzer Formation, Maastrichtian (72.1 - 66.0 Ma)

• "Maastrichtien" instead of Paleocene, as previously thought

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; poorly lithified, yellow marl

• "infralittoral conditions are developed in a waved environment evolving into a paralic inner domain eventually subject to freshening"
• "marines jaunes rapidement remplacés par de grès fins et jaunâtres" (yellow marls [170 and 175] quickly replaced by gray fine and yellowish sandstones [177])

Size class: microfossils
