We document diverse and well-preserved dinoflagellate cyst assemblages from Cretaceous successions in the Kullemölla 1 drill core (640.0 m–590.0 m), Vomb Trough, southern Sweden. Palynology reveals a nearshore marine environment. Dinoflagellate index taxa indicate an Albian to Coniacian age, thus spanning the Early–Late Cretaceous boundary. The lower part of the core is Albian, based on the presence of the index dinocyst taxa Pareodinia and Callaiosphaeridium asymmetricum. The First Appearance Datum (FAD) of Oligosphaeridium prolixispinosum, together with the presence of Achomosphaera ramulifera, Heterosphaeridium difficile and Oligosphaeridium pulcherrimum, reveals a Cenomanian age for the interval 635– m–617 m. The Turonian interval is characterized by an increase in the dinocysts Chatangiella spectabilis and Florentinia spp., in combination with the FAD of Senoniasphaera rotundata, whereas the youngest samples are dated to the Coniacian as defined by the appearance of Glaphyrocysta sp.

GFF 是瑞典地质学会的期刊。它是一本国际性的科学期刊，以英文发表论文，涵盖地质学和古生物学的整个领域，即岩石学、矿物学、地层学、系统古生物学、古地理学、历史地质学和第四纪地质学。化石、矿物和岩石的系统描述是 GFF 出版记录的重要组成部分。关于区域或地方地质学的论文应涉及波罗的斯堪地亚或北欧地质学，或与地质相关的领域。关于地球物理学、地球化学、生物地球化学的论文，气候学和水文学应该有地质背景。新方法（分析的、仪器的或数值的）的描述应该与期刊的广泛范围相关。欢迎评论文章，有时可能会征求意见。也可以提出主题问题。

GFF is a journal of the Geological Society of Sweden, serving as an international scientific publication that primarily publishes papers in English. The journal covers a wide range of fields within geology and paleontology, including petrology, mineralogy, stratigraphy, systematic paleontology, paleogeography, historical geology, and Quaternary geology. Systematic descriptions of fossils, minerals, and rocks are a significant component of GFF's publication record. Papers on regional or local geology should pertain to the Baltic or Nordic geology, or related fields. Papers addressing geophysics, geochemistry, biogeochemistry, climatology, and hydrology should have a geological background. Descriptions of new methods—whether analytical, instrumental, or numerical—should be relevant to the journal's broad scope. We welcome review articles and may occasionally solicit opinions, as well as proposals for thematic issues.
