摘要

Plax, D.P.和Newman, M. 2021。白俄罗斯中泥盆世棘足动物——新资料和区域间生物地层学。地质学报,71(4),393-414。华沙。白俄罗斯的下泥盆世(Emsian)和中泥盆世包含生物地层学上有用的动物和植物微遗骸组合。地表沉积物很少,大部分物质来自钻孔岩心。棘棘虫的鳞片特别多,与旧红砂岩大陆(Laurussia)的其他地区,特别是苏格兰的Orcadian Basin、波罗的海地区、斯匹次卑尔根岛和Severnaya Zemlya的鳞片相比,这些地区的棘棘虫物种有很多同义。白俄罗斯、奥卡迪亚盆地和波罗的海地区之间的情况尤其如此,这使我们能够制定一个区域间生物地层方案,并设想这些地区之间的海洋连接路线。白俄罗斯棘虫生物地层学特别重要,因为它与孢子和海洋无脊椎动物有关,因此不仅可以在旧红砂岩大陆上,而且可以在泥盆纪世界的其他地方提供更详细的相关性。我们还证明了保存的差异(例如,磨损和标本的铰接方式)是同义词的主要原因之一。

Middle Devonian acanthodians from Belarus – new data and interregional biostratigraphy
Plax, D.P. and Newman, M. 2021. Middle Devonian acanthodians from Belarus – new data and interregional biostratigraphy. Acta Geologica Polonica, 71 (4), 393–414. Warszawa. The Lower Devonian (Emsian) and Middle Devonian of Belarus contain assemblages of biostratigraphically useful faunal and floral microremains. Surface deposits are few, with most material being derived from borehole cores. Acanthodian scales are particularly numerous and comparison with scales from other regions of the Old Red Sandstone continent (Laurussia), specifically the Orcadian Basin of Scotland, the Baltic Region, Spitsbergen, and Severnaya Zemlya have demonstrated a lot of synonymy of acanthodian species between these areas. This is especially the case between Belarus, the Orcadian Basin and the Baltic Region, which has allowed us to produce an interregional biostratigraphic scheme, as well as to postulate marine connection routes between these areas. The acanthodian biostratigraphy of Belarus is particularly important as it is associated with spores and marine invertebrates, so giving the potential of more detailed correlations across not only the Old Red Sandstone continent, but elsewhere in the Devonian world. We also demonstrate that differences in preservation (e.g., wear and how articulated a specimen is) is one of the main reasons for synonymy.
