Where: Libya (29.2° N, 16.5° E: paleocoordinates 20.5° N, 12.6° E)
• coordinate stated in text
• local area-level geographic resolution
When: Al Jir Formation, Ypresian (56.0 - 47.8 Ma)
• The succession starts at the base with an 11 m (36 ft) bed of coarse-grained, wavy laminated anhydrite withtow interbeds of bioclastic dolomite, followed upward by a 19 m (62 ft) interval of porous, chalk dolomite with a large amount of poikilitic gypsum and intercalations of anhydrite, a 6 (20 ft) bed of anhydrite, and then by an 8 m (26 ft) section of gypsiferous dolomite at the top. The collect is from this uppermost dolomite. This unit overlies the Rouaga Member of the Beshima Formation and is overlain by the Al Gata Member of the Wadi Tamit Formation. Both contacts are gradational.
