摘要

本文在形态种的水平上详细描述了一个新的木材分类群——范德堡杉(Taxodioxylon vanderburghii 11 . spec.)。vanderburghii是第一个从斯匹次卑尔根第三纪建立的物种水平的木材。与现存单型种水杉(Metasequoia glyptostroboides) Hu & W. C. Cheng的木材比较表明，来自斯匹次卑尔根的化石材料(鉴定为T. vanderburghii 11 . spec.)代表水杉属(Metasequoia Hu & W. C. Cheng, 1948)。这是欧洲北极第三纪的第一个遗迹。全模含有范德伯氏菌化石树脂。用红外光谱对树脂进行了表征。为了比较起见，我们还对M. glyptostrobides的现代树脂和Glessite组的琥珀进行了FT-IR分析。

The fossil wood and resin of Taxodioxylon vanderburghii nov. spec. in Paleogene sediments of Svalbard

A new wood taxon, Taxodioxylon vanderburghii nov. spec., is described in detail on the level of morphospecies. T. vanderburghii is the first wood established on species level from the Spitsbergen Tertiary. Comparison with the wood of the living monotypic species Metasequoia glyptostroboides Hu & W. C. Cheng indicates that the fossil material from Spitsbergen, identified as T. vanderburghii nov. spec., represents the genus Metasequoia Hu & W. C. Cheng 1948. This is the first remain from the European Arctic Tertiary. The holotype contains fossil resin of T. vanderburghii. The resin was characterised by FT-IR spectroscopy. For comparative considerations, FT-IR analyses of the modern-day resin of M. glyptostroboides and of amber of the Glessite group were additionally conducted.

期刊介绍： Section B of Palaeontographica publishes contributions to palaeobotany, i.e. papers on morphological traits, systematics and phylogenetic features of plants as well as papers on palaeoclimatology and palynogeography. Especially worth mentioning are the comprehensive monographs published in Palaeontographica B on specific floras or plant groups. Often palaeoclimatic or stratigraphic problems are clarified by resorting to palaeobotanical data published in Section B of Palaeontographica. Throughout the last decades, numerous objects important to palaeophytology have been found in many places all over the world. As Palaeontographica publishes papers on floras on any parts of the world to report world-wide research, contributions in German, English and French have been published since the beginning of the journal, today English language publications are preferred. Palaeontographica B is of interest to palaeobotanists, palynologists, palaeoclimatologists, stratigraphers and the libraries of all institutions engaging in such research.
