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.展开更多
