This study presents the results of the conodont biostratigraphy and microfacies analysis carried out on the pelagic limestones of the Upper Triassic Dovško Section in Slovenia, which represents the eastern part of the Slovenian Basin. The age of the section ranges from the Lacian 1 to the Alaunian 1. The Lacian part of the succession is predominantly characterized by the representatives of the genus Ancyrogondolella. Transitional morphologies towards Alaunian faunas first appear in the Lacian 3 and become common during the Lacian-Alaunian transition. This evolutionary development coincides with a shift in microfacies from a dominantly radiolarian-bearing mudstone-wackestone-packstone to a filament- dominated wackestone-packstone, and the formation of small neptunian dykes, which may reflect environmental perturbations and/or a change in basin geometry. The proliferation of the genera Epigondolella and Mockina is observed in the Alaunian part of the section, though the genus Ancyrogondolella is still present in this interval. Systematic description of the conodont taxa is provided, and seven new species and two new subspecies are established. The new advances will be of great value in further biostratigraphic studies, especially in areas without ammonoid faunas, and in the reconstruction of the paleogeography of the Slovenian Basin.

这项研究提供了斯洛文尼亚上三叠纪Dovško剖面上层石灰岩进行的牙形石生物地层学和微相分析的结果，该剖面代表了斯洛文尼亚盆地的东部。该部分的年龄范围从Lacian 1到Alaunian1。该继承的Lacian部分主要以Ancyrogondolella属的代表为特征。。朝向Alaunian动物区系的过渡形态首先出现在Lacian 3中，并在Lacian-Alaunian过渡期间变得很普遍。这种演化的发展与微相从占主导地位的放射性放射状的泥岩-瓦克石-堆积石向以丝状为主的瓦克石-堆积石的转变以及海王星小堤的形成相吻合，这可能反映了环境扰动和/或盆地几何形状的变化。 。尽管在该部分的Alaunian部分观察到了Epigondolella和Mockina属的增殖，但Ancyrogondolella属在此间隔中仍然存在。提供了对牙形石分类群的系统描述，并建立了七个新物种和两个新亚种。新的进展将在进一步的生物地层学研究中，特别是在没有氨类动物区系的地区，以及在斯洛文尼亚盆地的古地理重建中，具有重要的价值。
