Hadjoula (SMNK collection) (Cretaceous of Lebanon)

Also known as Hjoula, Hgula, Hajula, Hadjula, Djoula

Where: Lebanon (34.1° N, 35.7° E: paleocoordinates 12.9° N, 30.4° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Sannine Limestone Formation, Late/Upper Cenomanian (99.6 - 93.5 Ma)

• Hjoûla Lagerstätte of the Sannine Limestone

• group of beds-level stratigraphic resolution

Environment/lithology: gray, calcareous mudstone

• During the Cretaceous Period the majority of the sediments were deposited within the Palmyride Basin, a large NNE–SSW trending intraplate trough, which persisted until the end of the Cretaceous when it was destroyed by regional compression. Within this basin the sediments slope westwards to form a single large monoclinal structure and the depositional environments are split between a western, open marine facies and an eastern, coastal facies (Nader et al. 2006).

•Saint-Marc (1974) described the palaeoenvironments of both Hâqel and Hjoûla during the Cenomanian as a small, oxygen depleted, marine basin, with the major land mass being located in the present WSW portion of the Arabian Peninsula. Nader et al. (2006) later described the depositional environment in the frame of a carbonate ramp model with shallower waters prevailing to the far east of Lebanon.
