A comprehensive study of the Late Devonian palynostratigraphy of Bjørnøya, Svalbard Archipelago is presented. A total of 61 samples collected from 10 outcrops located along the eastern coast of the island were analyzed for palynology yielding a mid- to latest Famennian age. A reassessment of the existing palynostratigraphy of the Ursa Sandstone Unit of the Røedvika Formation was undertaken. As no independent age control exists for this succession, the palynological assemblages were correlated to well-calibrated palynological zonations from the Eastern and Western Europe. The middle to upper part of the Vesalstranda Member and the Kapp Levin Member were assigned a mid- to late Famennian age (CVa to VF biozones), and the middle to lower-upper part of the Tunheim Member was dated as latest Famennian in age (LL to LN biozones). For the first time, a palynological age was assigned to the upper part of the Kapp Levin Member. Correlation with other Arctic areas show close resemblance to Late Devonian assemblages from Europe and the Arctic region. However, differences in the stratigraphical ranges of several taxa were identified. In terms of Late Devonian paleophytogeographic provinces the miospore assemblages are assigned to the Northern Euroamerican Cornispora varicornata Realm for the mid-Famennian. A more cosmopolitan trend was recognized for the latest Famennian (Strunian), with assemblages including abundant Retispora lepidophyta. The paleobotanical affinities of the palynomorphs reveal a flora of lycopods and progymnosperms occupying this area during the Late Devonian, with Retispora lepidophyta becoming a common element in the latest Famennian.

本文对斯瓦尔巴群岛的比约尔诺亚晚泥盆世古地层进行了全面的研究。从位于该岛东海岸的10个露头收集的总共61个样品进行了孢粉学分析，得出了中至最新的法门尼时代。对Rededvika组的Ursa砂岩单元的现有古地层进行了重新评估。由于该演替没有独立的年龄控制，故将古生物学组合与来自东欧和西欧的经过良好校准的古生物学分区相关联。Vesalstranda成员的中上半部和Kapp Levin成员被指定为中部至晚期的法门尼年龄（CVa至VF生物区），Tunheim成员的中下部至上半部的日期为最新的法门尼人年龄（ LL到LN生物区）。首次，卡普·莱文成员的上层被分配了一个古生物学年龄。与其他北极地区的相关性与来自欧洲和北极地区的晚泥盆纪的组合非常相似。但是，确定了几种分类单元的地层范围差异。就晚期泥盆纪古地理省而言，小孢子组合被分配给北美洲Cornispora varicornata领域，为法门尼中期。最新的法门尼人（Strunian）被认为是一种更加国际化的趋势，包括丰富的鳞翅目Retispora lepidophyta。古植物形态的古植物亲和力揭示了泥盆纪晚期，该地区存在着番茄科和裸子植物的菌群，而鳞翅目眼线虫（Retispora lepidophytyta）成为了最近的法门尼亚人的常见元素。
