Hadimopanellid Biostratigraphy in the Cambrian of the Western Taurids: A New Biostratigraphic Tool in the Subdivision of Cambrian System

Abstract: In the Cambrian of the Western Taurids six species of Hadimopanella has been found, five of them are new. Thesetaxa, Hadimopanella özgüli, H. ataseveri n.sp., H. inurselae n. sp., H. oskayi n. sp., H. saiti n. sp. and H. türkseni n.sp. are described and their startigraphic range determined. According to the startigraphic distribution of these taxa 6 new Hadimopanellabiozones has been established in the Cambrian System: From bottom to the top, these are: Hadimopanella ataseveri Interval-zone,H. ataseveri/H. oskayi Concurent range-zone, H. oskayi Interval - zone, H. türkseni Interval-zone, H. saiti/H. özgüli Assemblage-zone and H. inurselae Acme-zone.In addition, two new genera and species are named and described: Humboldtochaeta anatoliensis n. gen. n. sp. and Konyasphaerullda celali n. gen. n. sp.. The later one has a restricted stratigraphic range and is to be found in abundance in the Middle Cambrianstrata.
