El estudio de los ostrácodos de la transición Cenomaniense-Turoniense (Cretácico superior) en los Montes Ksour y Monte Amour (Atlas Sahariano, Argelia) ha permitido la identificación de asociaciones fósiles típicas de este periodo caracterizado por cambios ambientales a escala global. La asociacion de ostrácodos consiste en 15 especies y 7 géneros, y se encuentra dominada por la familia Cytherellidae (principalmente el género Cytherella), y en menor medida por las familias Paracyprididae (exclusivamente Paracypris) y Trachyleberididae (principalmente Cythereis). Las formas menos comunes corresponden a las familias Bairdiidae, Bythocypridae y Macrocyprididae. Las asociaciones de ostrácodos del Atlas Sahariano fueron comparadas con las asociaciones de cuencas vecinas pertenecientes a la provincia paleobiogeográfica del Norte de África y Oriente Medio (margen septentrional de Gondwana) con el fin de encontrar similitudes entre cuencas. Así, el resultado obtenido muestra una gran similitud entre la fauna de ostrácodos de las cuencas del Atlas Sahariano en Argelia y Túnez. Por otro lado, existe similaridad entre las asociaciones de las cuencas de Marruecos y Egipto, y de ambas a su vez con las cuencas de Oriente Medio (Jordán y Omán). Finalmente, la fauna de la Cuenca Libanesa aparece relativamente aislada. Estas similaridades entre distintas cuencas desde el punto de vista palaeobiogeográfico pueden evidenciar cierta comunicación entre las mismas o condiciones ambientales equivalentes durante el tránsito Cenomaniense-Turoniense.

“…Previous studies have proven an Albian-Cenomanian age for the Ifezouane Formation and a Cenomanian age for the Aoufous Formation [9,27,31], but their general continental and non-fossiliferous characters make their dating difficult in the absence of precise geochronological markers. However, the Akrabou Formation is dated as Cenomanian-Turonian based on biostratigraphic and isotopic δ 13 C data [6][7][8]11,13,15,18,24,32,33].…”

Lithostratigraphic, Paleoenvironmental Characterization and Correlations of the Albian–Turonian Deposits of the Errachidia–Boudnib–Erfoud Basin (Southeast Morocco)

Ten detailed sections have been logged and studied from the “Infra-Cenomanian’’ to the Cenomanian–Turonian deposits in the Errachidia–Boudnib–Erfoud Basin between Tazzouguerte and Anounizme(SE Morocco). They show variations in their lithology and microfacies that reflect changes in the depositional environment from the base to the top of the sedimentary record. Indeed, depositional setting grades from a fluvial environment marked by sandstone deposits of the Ifezouane Formation to an alluvial plain and coastal lagoon environment comprising an alternation of red clay, gypsum, and green marl beds of the Aoufous Formation and, finally, towards shallow to moderately deep marine environments with the deposition of the carbonates of the Akrabou Formation. Correlations between the studied sections show variations in the thickness of strata throughout the basin. The variations recorded in the so-called “Infra-Cenomanian” series may be related to the structuration of the basement. The Cenomanian–Turonian carbonate platform shows deeper marine and thicker sediments towards the east, while it thins towards the west until its disappearance in Anounizme. This reflects the global Cenomanian–Turonian transgression in the Errachidia–Boudnib–Erfoud Basin from the eastern Tethyan realm towards the west. The regional correlation of the Errachidia–Boudnib–Erfoud Basin with the Ouarzazate and Agadir basins shows an eastward thinning of the Cenomanian–Turonian marine deposits of Agadir. This suggests the presence of a paleorelief at the Anounizme locality. This could be the boundary between the Errachidia–Boudnib–Erfoud Basin, with Tethyan influence, to the east and those of Ouarzazate and Agadir, with Atlantic affinity, to the west.
