| IIn this research, the biostratigraphy of the Dalichai Formation in the Bar and Sarmeran sections at the Binalud Mountains has been studied with special emphasis on the most abundant ammonite family (Phylloceratidae family). The Dalichai Formation is mostly composed of marl, shale, siltstone, nodular marly limestone and limestone. In this study, by studying 219 specimens taken from the Bar and Sarmeran sections, ammonites belonging to 11 species, 4 Genus and 1 subgenus of the Phylloceratidae family have been identified. Based on the research completed, it is possible to consider an age equivalent to the Middle to Late Jurassic for the examined sequence of the Dalichai Formation in the Bar and Sarmeran sections. Paleobiogeographically, the existing ammonite fauna are closely related to the sub- Mediterranean Province of the northwestern Tethys. The Zigzag Zone of the Early Bathonian and the Bimammatum and Planula Zones of the Late Oxfordian have been recognized. | ||
