摘要

摘要对俄罗斯沃罗涅日和罗斯托夫地区的两个古近系岩心剖面以及乌克兰的一个露头进行孢粉学研究，发现了一种新的晚古新世-始新世物种——Carpatella rosica sp. nov.，由于其顶角和顶角的同时存在，该新种被归为Carpatella属。然而，认为该分类单元具有helene(1986)的“Aptiana-Ventriosum complex”的三个属之间的过渡性特征。本文根据对红藓属(Carpatella rosica sp. nov.)标本中薄而光滑的壁内层的观察，结合1988年以后描述的其他种的一些形态特征，提出了对红藓属(Grigorovich 1969) Damassa 1988的一个新的修正。

Carpatella rossica sp. nov., a new Late Paleocene–Eocene dinoflagellate species from European Russia and Ukraine

Abstract Palynological study of two Paleogene core sections from the Voronezh and Rostov regions (SW Russia) and one outcrop in Ukraine revealed the presence of a new Late Paleocene–Eocene species, Carpatella rossica sp. nov. The new species is attributed to the genus Carpatella because of the presence of both apical and antapical horns. However, it is suggested that the taxon represents some features transitional between the three genera of the “Aptiana–Ventriosum complex” of Helenes (1986). Based on the observation of a thin smooth inner layer of the wall in some specimens of Carpatella rossica sp. nov., and given some morphological features of other species described after 1988, a new emendation of the genus Carpatella (Grigorovich 1969) Damassa 1988 is proposed here.

期刊介绍： Acta Palaeobotanica is an international journal edited in English by the W. Szafer Institute of Botany, Polish Academy of Sciences, Kraków, since 1960, which publishes original palaeobotanical, palynological, palaeoecological and palaeophytogeographical papers, monographs, review and discussion articles and book reviews. It is the only journal in the Central and Eastern Europe publishing papers from all fields of palaeobotany. The journal is published regularly in one volume per year, with two numbers.
