Where: Morocco (33.6° N, 7.6° W: paleocoordinates 33.5° N, 7.9° W)
• coordinate based on nearby landmark
When: Late/Upper Miocene to Late/Upper Miocene (11.6 - 3.6 Ma)
• Rodents present suggest an age of 5.5-6Ma, near the Miocene/Pliocene boundary (Geraads 2011)
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; mixed carbonate-siliciclastic sediments
•Member 2: this is associated with a paleo-shoreline in a micro-cliff cut within Member 1; its facies characterizes an infratidal to supratidal environment; a basal conglomerate is visible resting on a substratum of quartzites at about 155m above present sea level; one observes a vertical and lateral transition to a capping aeolianite that conceals the relict shoreline and overlaps deposits of member 1; large bones of vertebrates are scattered in the eolianite. Towards the top of member 2, washout pockets contain a bioclastic sediment formed from the remains of biocalcarenite, rich in bony fragments of micro-mammals and larger vertebrates.'
