Coordinates: 31.9° North, 4.9° West (view map)
Paleocoordinates:20.2° North, 4.8° West
Basis of coordinate:stated in text
Geographic resolution:local area
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Stage:Turonian 10 m.y. bin:Cretaceous 6
Key time interval:Early/Lower Turonian Ammonoid zone: Mammites nodosoides
Age range of interval:93.90000 - 89.80000 m.y. ago
Stratigraphy
Formation:Akrabou
Stratigraphic resolution:group of beds
Stratigraphy comments: These concretions contain a diverse ammonite fauna (Kennedy et al. 2008) indicative of the Mammites nodosoides biozone of the early Turonian (Cavin & Dutheil 1999). Where fossils are actively mined, there are typically two distinct units of concretions. A lower concretion bed, up to 1 metre thick, is generally poor in macrofossils although some ammonites are present. A second concretion bed, about 2 metres higher in the succession, is somewhat discontinuous (being absent at this level at Asfla itself) and often highly fossiliferous.
