Where: Morocco (32.5° N, 2.0° W: paleocoordinates 24.0° N, 2.0° W)

• coordinate based on nearby landmark

When: Hettangian to Hettangian (201.3 - 190.8 Ma)

Environment/lithology: reef, buildup or bioherm; dolomitic reef rocks

• les depots recifaux ou subrecifaux debutent des le Lias inferieur; ils sont amorces par des constructions de buttes de boue carbonatee, souvent dolomitisee et construites a partir d'organismes autres que les Madreporaires (Algues, Spongiaires). (interpreted as the reefs and subreef deposits begin in the lower Lias; they begin with the construction of carbonate mud mounds, which are often dolomitized and are composed in part of organisms other than coral (algae, sponges))

Size class: macrofossils
