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.
