ABSTRACT. A small early Late Viséan (Mississippian) ammonoid assemblage with Entogonites saharensis new
  species md Goniatites lazarus new species is described from the eastern Anti-Atlas of Morocco, being the first African
  record of Entogonites.  The family Goniatitidae is a typical Lazarus taxon, which, after a gap representing approximately
  10 million yeus, reappears in the fossil record. The genera Entogonites and Goniatites have a wide paleogeographic
  distribution (northwest Laurentia, northern and southern Variscides, north Gondwana). This indicates ammonoid
  cosmopolitism at the genus level at the end of the middle Viséan, before late Viséan ammonoid provinces formed.  
  Entogonites with tetrangularly coiled juvenile whorls and with a low aperture probably had a planktonic life- style.
