Hadjoula (Day collection, AMNH) (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

• outcrop-level geographic resolution

When: Late/Upper Cenomanian (99.6 - 93.5 Ma)

• Hjoûla Cretaceous limestone

• group of beds-level stratigraphic resolution

Environment/lithology: lithified limestone

• The limestone sedimentation including fossils is not flat: in fact, bending and fractures, with frequent shifting, are common events within very small areas at the Hgula quarries. This non-homogeneous limestone configuration does not permit the recovery of large slabs of limestone. On the other hand, the Hgula limestone is characterized by an impressive richness: dozen of fossil fishes almost completely cover each limestone surface, with frequent overlapping of individual specimens. The most frequent fossils are undoubtedly fishes, but shrimps are also very common.

Size class: macrofossils
