Abstract

The genus Trinovantedinium Reid 1977 comprises eleven NeogeneQuaternary and one Paleogene dinoflagellate cyst taxa that have been successfully used for biostratigraphy. Combining new and published records of Trinovantedinium species in the Neogene of the tropical Americas, we report preliminary stratigraphic ranges for T. applanatum (AquitanianRecent), T. ferugnomatum (BurdigalianZanclean), T. glorianum (BurdigalianMessinian), T. papula (AquitanianZanclean), T. uitpensis (AquitanianTortonian), T. variabile (AquitanianRecent) and T.? xylochoporum (AquitanianMessinian) in the region. Although the stratigraphic ranges of T. applanatum, T. variabile and T.? xylochoporum in the tropical Americas seem to be coetaneous with previous records elsewhere, the first appearance datums of T. ferugnomatum, T. glorianum and T. papula seem to be at least ∼ 2–3 Myr. older in the tropical Americas. In contrast, only the last appearance datum of T. glorianum seems to be ∼ 4 Myr. younger in the Northern Hemisphere. Our results demonstrate that the Cenozoic marine palynological record of the tropical Americas is therefore key to discriminate dinoflagellate cyst stratigraphic ranges across latitudes.

美洲热带地区新近纪甲藻胞囊属 Trinovantedinium Reid 1977 的记录

Trinovantedinium Reid 1977 属包括 11 个新近纪第四纪和 1 个古近纪甲藻胞囊类群，这些类群已成功用于生物地层学研究。结合美洲热带地区新近纪 Trinovantedinium 物种的新记录和已发表的记录，我们报告了 T. applanatum（阿奎坦纪近期）、T. ferugnomatum（布迪加利亚-赞克林）、T.t.uitpensis（阿奎坦-托尔托尼世）、T. variabile（阿奎坦-新生代）和 T.? xylochoporum（阿奎坦-梅西尼亚世）的初步地层范围。虽然 T. applanatum、T. variabile 和 T. xylochoporum 在美洲热带地区的地层范围似乎与其他地区以前的记录一致，但 T. ferugnomatum、T. glorianum 和 T. papula 在美洲热带地区的首次出现日期似乎至少要早 2-3 Myr.。相比之下，只有T. glorianum在北半球的最后出现时间似乎比现在年轻4 Myr.。我们的研究结果表明，美洲热带地区新生代海洋古生物学记录是区分不同纬度地区甲藻囊地层范围的关键。

期刊介绍： The Review of Palaeobotany and Palynology is an international journal for articles in all fields of palaeobotany and palynology dealing with all groups, ranging from marine palynomorphs to higher land plants. Original contributions and comprehensive review papers should appeal to an international audience. Typical topics include but are not restricted to systematics, evolution, palaeobiology, palaeoecology, biostratigraphy, biochronology, palaeoclimatology, paleogeography, taphonomy, palaeoenvironmental reconstructions, vegetation history, and practical applications of palaeobotany and palynology, e.g. in coal and petroleum geology and archaeology. The journal especially encourages the publication of articles in which palaeobotany and palynology are applied for solving fundamental geological and biological problems as well as innovative and interdisciplinary approaches.
