Abstract

Abstract. Botrychiopsis is an important biostratigraphic index taxon for Carboniferous–early Permian plant fossil successions of Gondwana. Its species have wide geographic distributions, restricted chronostratigraphic ranges, and are associated with diverse groups of plant associations. They have been described from sedimentary sequences of Australia, India, South Africa, Brazil, and Argentina. A whole-frond reconstruction of Botrychiopsis plantiana is presented based on a study of very well preserved specimens from the Gangamopteris flora (Ghzelian–Asselian) of the Bajo de Véliz Formation (Paganzo Basin, Argentina). The material consists of impressions of complete fronds and basal fragments, which are rarely represented in the Gondwanan upper Paleozoic fossil record.

冈瓦纳大陆最西部葛里阶-西苏里阶的一个关键种植物Botrychiopsis plantiana的修订

摘要芽孢藓是冈瓦纳石炭纪-早二叠世植物化石演替的重要生物地层指标分类群。其物种地理分布广泛，年代地层范围有限，并与多种植物类群相关联。它们在澳大利亚、印度、南非、巴西和阿根廷的沉积序列中被描述过。基于对阿根廷Paganzo盆地Bajo de vsamuliz地层Gangamopteris植物区系(Ghzelian-Asselian)保存完好的标本的研究，提出了plantiana Botrychiopsis的整体重建。材料由完整的叶状印痕和基底碎片组成，这在冈瓦南上古生界化石记录中是罕见的。

期刊介绍： Ameghiniana is a bimonthly journal that publishes original contributions on all disciplines related to paleontology, with a special focus on the paleontology of Gondwana and the biotic history of the southern hemisphere. Published yearly since 1957, it has undoubtedly become the main palaeontological publication from Latin America. Ameghiniana has recently broadened its editorial board, reorganized its production process, and increased to a bimonthly frequency, which resulted in a significant decrease in the turn around time.
