Abstract Dinoflagellate resting cysts with rare exception produce the only discrete link between the biology of extant dinoflagellate species and their fossil record. The geological preservability of such cysts allows them to be used for quantitative paleoecological reconstructions, especially in the Quaternary, and for biostratigraphy and the calibration of molecular clocks with the geological record. This contribution reviews and updates the taxonomy of 27 uncommon dinoflagellate cyst species and morphotypes belonging to the orders Gonyaulacales and Suessiales with occurrences in upper Quaternary marine sediments of the Northern Hemisphere. Comparative descriptions and illustrations are provided along with the biological affinity of each taxon where known and lowest stratigraphic occurrence.

对来自北半球的 Gonyaulacales 和 Suessiales 目的罕见和鲜为人知的现存海洋有机壁甲藻孢囊分类群的回顾

摘要 甲藻静息囊肿产生了现存甲藻物种的生物学与其化石记录之间的唯一离散联系。这种包囊的地质可保存性使其可用于定量古生态重建，特别是在第四纪，以及用于生物地层学和分子钟与地质记录的校准。本贡献回顾并更新了 27 种不常见的甲藻囊肿物种和形态类型，这些物种属于 Gonyaulacales 和 Suessiales 目，它们出现在北半球上第四纪海洋沉积物中。提供了比较描述和插图以及已知和最低地层出现的每个分类群的生物学亲和力。
