Hakel (Cope collection) (Cretaceous of Lebanon)

Also known as Haqel, Haqil; Niobrara Cretaceous of Dakota; Yankton

Where: Lebanon (34.2° N, 35.8° E: paleocoordinates 13.0° N, 30.4° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Metoicoceras geslinianum ammonoid zone, Late/Upper Cenomanian (99.6 - 93.5 Ma)

• The precise age of Hâqel and Hjoûla varies according to different authors. ln his comprehensive sedimentological study Hückel (1970) divided the Cenomanian Limestones into seven units and concluded that Hâqel (unite V) and Hjoûla (unite IV) were deposited during the later Lower Cenomanian. Owing to the occurrence of the ammonite Allocrioceras annulatum as a member of the Metoicoceras geslinianum Zone, Wippich & Lehmann (2004) confirmed the conclusions of Hemleben (1977) and dated Hâqel and Hjoûla as Upper Cenomanian (Fig. 2). Dalla Vecchia et al. (2002) considered Hâqel and Hjoûla as lower Upper Cenomanian, because Nammoûra (another fossil-rich locality a few kilometres in the South of Hjoûla and slightly younger than Hâqel and Hjoûla) is dated as Middle Cenomanian.
