Late Triassic (Julian) conodont biostratigraphy of a transition from reefal limestones to deep-water environments on the Cimmerian terranes (Taurus mountains, southern Turkey)

Sections at Aşağiyaylabel and Yukariyaylabel, Taurus Mountains, southern Turkey, provide a rare opportunity to investigate conodont faunas in detail across a reef to slope transition. Intensive sampling of limestone beds (wackestones to packstones) through approximately 3 m at these locations has led to the recognition of a new lower Carnian (Julian 1/2) conodont fauna within the Kartoz and Kasimlar formations. Members of the subfamilies Paragondolellinae and Pseudofurnishiinae are recognized. The genus Kraussodontus is reported for the first time from the Taurus Mountains. Mosherella postkockeli and Mosherella praebudaensis sp. nov. occur within the lower Carnian Carbonate Member of the Kasimlar Formation from the Taurus Platform Units. The discovery of the new conodont assemblages from Aşağiyaylabel and Yukariyaylabel facilitates a correlation with faunal assemblages worldwide.土耳其南部托罗斯山脉的下亚拉贝尔（Aşağıyaylabel）与上亚拉贝尔（Yukariyaylabel）剖面，为详细探究礁体至斜坡过渡带的牙形石（conodont）动物群提供了绝佳契机。研究人员对两处点位约3米厚的石灰岩地层（灰泥岩（wackestone）至颗粒灰泥岩（packstone））开展了密集采样，在卡尔托兹组（Kartoz Formation）与卡斯姆拉尔组（Kasimlar Formation）中识别出一个全新的卡尼阶早期（朱利安阶1/2亚期）牙形石动物群，涵盖副冈多勒亚科（Paragondolellinae）与假弗尔尼什亚科（Pseudofurnishiinae）的类群。克劳斯牙形石属（Kraussodontus）为托罗斯山脉地区的首次报道。在托罗斯台地单元（Taurus Platform Units）的卡斯姆拉尔组下卡尼阶碳酸盐岩段中，产出了莫舍拉属（Mosherella）的Mosherella postkockeli以及新种（sp. nov.）Mosherella praebudaensis。此次在下亚拉贝尔与上亚拉贝尔发现的全新牙形石组合（conodont assemblage），可助力开展全球范围内的动物群组合对比研究。
