biostratigraphy late early cambrian - late cambrian successions in kamar siah section (southeast kerman) on the basis of trilobites

cambrian sediments are widely exposed in the kerman province. parts of these deposits are containing trilobite fossils. one of the suitable areas for paleontological studies is kamar siah section. this section located about 60 km north east of kerman. these sediments have 200 m thickness with fossil invertebrates of trilobites, brachiopod, gastropods and stromatolite which includes kuhbanan and unnamed formations. in this study, 17 genera and 11 species of trilobites were identified and described that include afghanocera lategenatum, anomocarella chinensis, anomocarella sp., blountia blountia, cheliedonocephalus farsia, iranoleesia pisiformis, kermanella lata lata, kermanella lata minuta, kermanella sp., kobayashiella sp., latouchella? huckriedea, paragralous? dahuensis, redlichia cf. chinensis redlichia noetlingi, redlichia sp., stoecklinaspinosa, syspachelius sp. based on trilobite assemblages, kamar siah section is divided by four trilobite biozones: redlichia noetlingi biozone, kermanella kuhbananensis biozone, iranoleesia pisiformis biozone, cheliedonocephalus farsia biozone. three biozone belong to kuhbanan formation and one biozone belong to unnamed formation. the age of this section, based on trilobite biozone, is late early cambrian to early late cambrian.
