This article compiles data on the Devonian-Carboniferous Boundary successions from countries and regions, which have not been dealt with separately in this special issue. Data derive from different palaeocontinents on a large palaeoclimatic gradient from the southern high latitudes of western Gondwana through the palaeotropics into the temperate/boreal northern latitudes of Siberia. The quality of the data is variable, but often surprisingly good, although major uncertainties can persist and traditional positions of the boundary do not withhold modern stratigraphic results and concepts. Not all these regions have been on the forefront of the DCB discussions in recent years, but they provide invaluable insights into the regional and global dimensions of uppermost Devonian and lowermost Carboniferous changes in the biosphere and geosphere. Almost globally documented are faunal turnovers and collapse of ecosystems in the Hangenberg extinctions. Those allow the placement of the DCB even if index fossils are absent or scarce. However, it also shows the regional differences, which advocate for a holistic approach to the boundary by ensuring global correlation without relying on the conceptual dominance a single taxon, which might be less powerful outside its usual facies.

全球范围内的泥盆纪-石炭纪边界:补充

本文汇总了本期未单独论述的国家和地区泥盆纪-石炭纪界线演替资料。数据来自于大古气候梯度上的不同古大陆,从冈瓦纳西部的南部高纬度经古热带到西伯利亚的温带/北方北纬。数据的质量是可变的,但通常出奇地好,尽管主要的不确定性可能会持续存在,并且边界的传统位置不会保留现代地层学结果和概念。近年来,并非所有这些地区都处于 DCB 讨论的前沿,但它们为生物圈和地圈中最上层泥盆纪和最下层石炭纪变化的区域和全球层面提供了宝贵的见解。几乎在全球范围内都有记载的是汉根堡大灭绝中动物群的更替和生态系统的崩溃。即使索引化石不存在或稀少,这些也允许放置 DCB。然而,它也显示了区域差异,它提倡通过确保全球相关性而不依赖单个分类群的概念优势来对边界采取整体方法,这在其通常的相貌之外可能不那么强大。
