Abstract The Pennsylvanian flora from the Italian Carnic Alps, stored in the Museo Friulano di Storia Naturale in Udine, Italy, was revised taxonomically. Plant fossils come from the Bombaso Formation and Pramollo (Auernig) Group (Late Pennsylvanian) that correspond to the lower part of the paralic to shallow marine Carboniferous–Permian Pramollo (or Pramollo-Nasfeld) Basin succession. Most of the ~ 2500 studied plant fossils and also the highest number of species come from the the Bombaso, Meledis and Pizzul formations, whereas the middle and upper part of the Pramollo Group in the Italian Carnic Alps yielded only few plant remains, contrarily to the successions on the Austrian side. In total 73 plant taxa have been identified, which represent about 59 biological species. The ferns, especially marattialen ferns, are the most diverse plant group (33 species in total) followed by pteridosperms (15 species). The stratigraphic range of the Bombaso Formation and the Pramollo Group have been re-evaluated based on presence of stratigraphically important species from both the Italian and Austrian parts of the Carnic Alps. The studied interval ranges from a middle Barruelian to middle Stephanian B sensu Wagner and Alvarez-Vazquez (2010a) and spans about 3.5 Ma. The diversity of the Carnic Alps flora is comparable with well-documented contemporaneous floras in NW Spain, French Massif Central and the Czech Republic. Floral richness and diversity together with intercalations of plant-rich horizons with fossiliferous marine limestone bands makes the Carnic Alps a potential candidate as a stratigraphically important reference section for non-marine to marine correlations.

意大利卡尔尼克阿尔卑斯山的宾夕法尼亚晚期植物群

摘要 在意大利乌迪内的 Museo Friulano di Storia Naturale 保存的来自意大利 Carnic 阿尔卑斯山的宾夕法尼亚植物群进行了分类学修订。植物化石来自 Bombaso 组和 Pramollo (Auernig) 群（宾夕法尼亚晚期），它们对应于近海到浅海石炭纪-二叠纪 Pramollo（或 Pramollo-Nasfeld）盆地序列的下部。研究的约 2500 种植物化石中的大部分以及数量最多的物种来自 Bombaso、Meledis 和 Pizzul 地层，而意大利卡尼克阿尔卑斯山的 Pramollo 群的中部和上部仅产生了少量植物遗骸，与奥地利方面的继承。共鉴定了 73 个植物类群，代表了大约 59 个生物物种。蕨类植物，尤其是马拉蒂亚伦蕨类植物，是最多样化的植物群（总共 33 种），其次是蕨类植物（15 种）。Bombaso 组和 Pramollo 组的地层范围已根据来自 Carnic 阿尔卑斯山的意大利和奥地利部分的地层重要物种的存在进行重新评估。研究的区间范围从中巴鲁埃阶到中斯蒂芬阶 B sensu Wagner 和 Alvarez-Vazquez (2010a)，跨度约为 3.5 Ma。卡尼克阿尔卑斯山植物群的多样性与西班牙西北部、法国中部和捷克共和国有据可查的同期植物群相当。
