Fezouata Formation

The Upper and Lower Fezouata Formations of Morocco are Burgess shale-type deposits dating to the Early Ordovician, filling an important preservational window between the common Cambrian Lagerstätten and the Late Ordovician Soom Shale. Found fossilized fauna were numerous organisms previously thought to have died out after the mid-Cambrian.
