The Upper and Lower Fezouata formations of Morocco are Burgess Shale type deposits dating to the Lower Ordovician. In the fossilized fauna were numerous organisms previously thought to have died out after the mid-Cambrian. The discovery proves conclusively that the Burgess Shale biota did not go extinct in the Cambrian.
