Abstract

Abstract An acanthodian assemblage is reported for the first time from the Silurian–Devonian boundary beds of Novaya Zemlya Archipelago, Russia. The acanthodian scales and rare other vertebrate microremains were in a sample collected from the Reliktovoe Formation of the western coast of Inostantzev Bay, North Island. The assemblage includes Gomphonchus mediocostatus, Gomphonchoporus hoppei taxa previously described from the Pridoli – Lochkovian of Laurussia, and Taimyrolepis composita occurred in the Lochkovian of Siberia. Gomphonchus mediocostatus and Gomphonchoporus hoppei are widely distributed in the Baltica palaeogeographic province, and Taimyrolepis is known from the Siberia province, indicating connection between those provinces.
俄罗斯新地岛群岛志留纪-泥盆纪交界层的刺蜥
摘要首次报道了俄罗斯新地岛群岛志留系-泥盆系界线层的刺蜥岩组合。棘棘目鳞片和其他罕见的脊椎动物微遗骸是在北岛伊诺斯坦采夫湾西海岸的Reliktovoe组收集的样本中发现的。该组合包括先前在Laurussia Pridoli - Lochkovian发现的Gomphonchoporus hoppei类群,以及在西伯利亚Lochkovian发现的Taimyrolepis composita。Gomphonchus mediocostatus和Gomphonchoporus hoppei广泛分布于波罗的海古地理省,而Taimyrolepis则来自西伯利亚省,说明了这两个省之间的联系。

期刊介绍: GFF is the journal of the Geological Society of Sweden. It is an international scientific journal that publishes papers in English covering the whole field of geology and palaeontology, i.e. petrology, mineralogy, stratigraphy, systematic palaeontology, palaeogeography, historical geology and Quaternary geology. Systematic descriptions of fossils, minerals and rocks are an important part of GFF''s publishing record. Papers on regional or local geology should deal with Balto-Scandian or Northern European geology, or with geologically related areas. Papers on geophysics, geochemistry, biogeochemistry, climatology and hydrology should have a geological context. Descriptions of new methods (analytical, instrumental or numerical), should be relevant to the broad scope of the journal. Review articles are welcome, and may be solicited occasionally. Thematic issues are also possible.
