Nahal Zin (level 4b) (Cretaceous of Israel)

Where: Israel (30.8° N, 35.1° E: paleocoordinates 13.8° N, 30.4° E)

• coordinate stated in text

• outcrop-level geographic resolution

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

• Very top of phosphate layer No. V (top Mishash Fm). Phosphate layer V in the Oron and Nahal Zin regions, 80-100 cm thick, directly overlies a more finely laminated phosphate layer (IV) of the same thickness, in which Lyropecten (Aequipecten) acuteplicatus (Alth) (= Pecten farafrensis Zittel) first appears, known in Europe from the Maastrichtian only (Dhondt 1972). In southern Israel it overlies another phosphate complex of 3 m, which decreases in thickness northwards to a few centimeters in the Oron region. Calcareous beds in this complex contain Baculites cf. B. anceps Lamarck (ornate form). However, upper Mishash Formation dated to Late Campanian on the basis of nannofossils (zone NC20) by Eshket & Moshkovitz, 1995.
