The deposits of the Carnian Kasımlar Formation within the Taurus Platform Units of south‐western Turkey represent an important archive of a Late Triassic ecosystem. New palaeontological information was obtained by analysing the Kasimlarceltites mass occurrence, located within the Kasımlar Formation and named after the Lower Carnian (Julian) ammonoid genus Kasimlarceltites. This is the dominant taxon (> 94%) within the mass occurrence: nearly 775 million ammonoids and 50 million gastropods were extrapolated for the whole extension (at least 5 km2) of the Kasimlarceltites beds. This calculation is one of the main findings within this study, as it is the first time that such a fossil mass occurrence was quantified. Additionally, orientation measurements of the planispiral ammonoids and the helical gastropods enabled reconstructing the history of the mass occurrence and interpreting the underlying transport mechanisms. Further taphonomic aspects (e.g. biofabric, preservation, bioerosion or genetic classification) as well as comparisons with samples of the same acme zone from different localities near Aşağiyaylabel (AS IV, KA I‐II) point to a two‐phased genetic history. Accordingly, local mass mortality within the Kasimlarceltites fauna due to oxygen fluctuations or methane degassing may have initially led to a primary accumulation. These deposits were then reworked and redeposited basinward by gravity flows to create the present‐day secondary allochthonous concentrations.

土耳其 Taurus 山脉晚三叠世 (Carnian) 菊石浓度的埋藏学和古生态学

土耳其西南部 Taurus 地台单元内的 Carnian Kasımlar 组沉积物代表了晚三叠世生态系统的重要档案。通过分析位于 Kasımlar 组内并以下卡尼阶 (Julian) 菊石属 Kasimlarceltites 命名的 Kasimlarceltites 群落，获得了新的古生物学信息。这是大量发生中的主要分类群 (> 94%)：对 Kasimlarceltites 床的整个延伸范围（至少 5 平方公里）外推了近 7.75 亿个菊石和 5000 万个腹足动物。该计算是本研究的主要发现之一，因为这是第一次对这种化石质量的发生进行量化。此外，Planispiral ammonoids 和螺旋腹足动物的方向测量能够重建大规模发生的历史并解释潜在的运输机制。进一步的埋藏学方面（例如生物结构、保存、生物侵蚀或遗传分类）以及与来自 Aşağiyaylabel（AS IV、KA I-II）附近不同地点的同一顶点区域的样本的比较表明了一个两阶段的遗传历史。因此，由于氧气波动或甲烷脱气导致 Kasimlarceltites 动物群内的局部质量死亡可能最初导致了初级积累。然后这些沉积物通过重力流重新加工并重新沉积到盆地中，以形成当今的次生异地浓度。G。生物纤维、保存、生物侵蚀或遗传分类）以及与来自 Aşağiyaylabel（AS IV、KA I-II）附近不同地点的同一顶点区域的样本的比较表明了一个两阶段的遗传历史。因此，由于氧气波动或甲烷脱气导致 Kasimlarceltites 动物群内的局部质量死亡可能最初导致了初级积累。然后这些沉积物通过重力流重新加工并重新沉积到盆地中，以形成当今的次生异地浓度。G。生物纤维、保存、生物侵蚀或遗传分类）以及与来自 Aşağiyaylabel（AS IV、KA I-II）附近不同地点的同一顶点区域的样本的比较表明了一个两阶段的遗传历史。因此，由于氧气波动或甲烷脱气导致 Kasimlarceltites 动物群内的局部大规模死亡可能最初导致了初级积累。然后这些沉积物通过重力流重新加工和重新沉积到盆地中，以形成当今的次生异地浓度。由于氧气波动或甲烷脱气，Kasimlarceltites 动物群内的局部大规模死亡可能最初导致了初级积累。然后这些沉积物通过重力流重新加工和重新沉积到盆地中，以形成当今的次生异地浓度。由于氧气波动或甲烷脱气，Kasimlarceltites 动物群内的局部大规模死亡可能最初导致了初级积累。然后这些沉积物通过重力流重新加工并重新沉积到盆地中，以形成当今的次生异地浓度。
