SN - 00166995 KW - Carboniferous KW - Siphonodella hassi KW - Siphonodella wilberti KW - Siphonodella jii KW - Siphonodella duplicata sensu Hass UR - https://www.sciencedirect.com/science/article/pii/S0016699521000012 N2 - Traditionally, biostratigraphy of the terminal Famennian (Upper Devonian) and lower part of the Tournaisian (Mississippian) is based on phylogeny of the conodont genus Siphonodella Branson and Mehl. This study is focused on a Siphonodella species with a long taxonomical history. For the last three decades it was known as S. hassi Ji, 1985 and was used as a zonal index for the eponymic hassi Zone, used worldwide. However, this species faces several taxonomical problems. The main issue is the homonymy of S. hassi and S. cooperi hassi Thompson and Fellows, 1970. However, S. cooperi hassi is a subjective junior synonym of S. obsoleta Hass, 1959. The oldest junior synonym of S. hassi is S. wilberti Bardasheva, Bardashev, Weddige and Ziegler, 2004, and, according to a statement by the International Commission on Zoological Nomenclature, the latter represents the only available name for this species. An additional problem is the similar morphology of early ontogenetic stages of S. wilberti and S. quadruplicata Branson and Mehl, 1944, the youngest stratigraphically important siphonodellid species. In advanced ontogenetic stages, P-1 elements that possess two rostral ridges belong to S. wilberti only. The smaller P-1 elements having two or less rostral ridges comprise the S. wilberti-S. quadruplicata plexus. Maintenance of the wilberti Zone in the Tournaisian global zonation is suggested. ER -
