The Fezouata Biota Received 30 September 2015 from the Lower Ordovician of Morocco is a Konservat-Lagerstätte of major importance, and it is today considered Accepted 29 October 2015 as an ‘Ordovician Burgess Shale.’ This biota was discovered only some 15 years ago, but geological studies of the Available online 10 November 2015 area date back to the beginning of the 20th century.
