Abstract
    For the first time the complete conodont fauna from the GSSP for the base of the Givetian at Jebel Mech Irdane in the Tafilalt (SE Morocco) is described. The conodont faunas described by Bultynck in 1987 from the Bou Tchrafine ridge in the same area and from the Jebel Ou Driss (Mader, SE Morocco) in 1989 are updated. Many new morphotypes of Polygnathus linguiformis and other conodont species are described. Polygnathus amphora, P. pseudoeiflius and Icriodus hollardi are established as new species.
