Upper cretaceous foraminiferal biostraigraphy and paleobathymetry of the Al-Baqa area, North of Amman (Jordan)
The examination of vertical variations of foraminiferal assemblages in the Upper Cretaceous exposures of the Al-Baqa area to the north of Amman in Jordan enables us to evaluate ancient paleobathymetric changes with regard to eustatic changes in sea level. Index foraminiferal species are used for age determinations and paleobathymetry.
The sedimentary cycle including Upper Cenomanian sediments (Fuheis, Hummar, Shueib and Wadi Sir Formations) appears to be related to global eustatic changes in sea levels. This is also the case of the Late Campanian sedimentary cycle in the study area (Amman Formation).
