摘要
本文首次描述山东东营凹陷晚更新世海侵层中的沟鞭藻类化石 12种含 1亚种 1比较种和 1新种 (Dissilio-dinium tuberculatum sp.nov.) ,归属于 6属 3科 ;简要介绍了沟鞭藻组合特征。
Dinoflagellate assemblage from Late Pleistocene transgression beds in Dongying depression, Shangdong Province is reported for the first time in this paper. A total of 6 genera and 12 species are described and illustrated, including 1 new species, Dissiliodinium tuberculatum, 1 subspecies, 1 variety and 7 indeterminate species. The assemblage is characterized by a less high diversity and low cyst abundance. It is composed almost entirely of gonyaulacoid cysts and dominanted by the species of Spiniferites. The fossils found are poorly preserved, most specimen are only preliminarily identified. The main elements are Achomosphaera sp., Impagidinium cf. aculeatum, Spiniferites elongatus , Spiniferites ramosus, Spiniferites bentorii subsp.truncatus, Spiniferites spp., Operculodinium centrocarpum, Tuberculodinium vancampoae, Dissiliodinium tuberculatum sp. nov., Quinguecuspis? sp., Gonyaulacysta? sp. ect.
