In order to systematically study the trace fossils of Upper Cretaceous flysch deposits, Golbaf stratigraphic section in the southeast of Kerman province was selected and sampled. These deposits are 147 meters’ thickness and consist of siltstone, silty sandstone and shale. From Golbaf stratigraphic section, 68 ichnospecies belonging to 30 ichnogenera have been studied and identified, according to the abundance of trace fossils in the section, Planolites isp., Paleophycus isp., Ophiomorpha rudis, Thalassinoides suevicus, Helminthopsis isp., Helminthorhaphe felxcous, Cochlichnus isp., Cosmorhaphe isp., Zoophycos isp. and Paleodictyon strozzii. Based on the diversity of identified fossils, the age of the flysch deposits in the Golbaf Coniacin-Santonian section is suggested. These fossils mostly include crawling-nutritional or nutritional effects. The variety and abundance of trace fossils in the section under study shows the appropriate environmental and ecological conditions at the time of the deposition of sediments. These fossils are found in a shallow to turbidity marine environment, which is well preserved and varied, and their highest abundance is seen in the middle part of this section.
