Sample C2, Wạwał clay pit (Cretaceous of Poland)

Also known as Wawal

Where: Lodzkie, Poland (51.5° N, 20.1° E: paleocoordinates 43.1° N, 26.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Saynoceras verrucosum ammonoid zone, Late/Upper Valanginian (140.2 - 136.4 Ma)

• Unit 11, Late Valanginian, upper hollwendensis / lower verrucosum zone
