The Thanetian phosphatic series of Jebel Dyr syncline, northeastern Algeria, are analyzed for their paleontological content. Materials were concentrated by sample washing and outcrops surface collecting of friable phosphorites facies, yielding a multitude of phosphatised fish teeth rich in species of variable morphology, representing 28 species of Elasmobranchii. The fish fauna indicates tropical to temperate paleo-environmental conditions. Most of the species represent benthic/nektonic forms of coastal areas with neritic and midwater depths of the continental slope.
