摘要

摘要 Himgir 子盆地位于印度奥迪沙伊布河盆地的西南部。研究人员沿着奥迪沙邦孙达尔加尔区 Himgir 村附近的路段勘探了下冈瓦纳化石地层,并报告了包括翼手目和裸子植物在内的植物大化石(1002 个标本)、4 个植物类群、10 个属和 55 个物种。翼手目植物(Equisetales、Sphenophyllales 和 Filicales)的代表有 Schizoneura gondwanensis Feistmantel, 1876、马尾茎、Trizygia speciosa Royle, 1839 和 Neomariopteris talchirensis Maithy, 1974。裸子植物中只有一个植物类群,即 Glossopteridales(46 种 Glossopteris)以及茎杆、果实和鳞片叶。二叠纪晚期植物群的出现、该植物群中缺乏三叠纪时期特有的单子叶植物群,以及调查地点的红色地层(铁锈色红色砂岩和铁锈色红色页岩)表明,该出露地层属于下卡姆蒂地层,属于武契亚平纪至长兴纪时期。大型植物群落表明该地区气候温暖湿润,雨量充沛,光照强度适中。还对所研究的次盆地的植被进行了研究,以描绘该地区的古生物多样性。

Biodiversity of Himgir Sub-Basin, India during Late Permian: A Comprehensive Study

Abstract

The Himgir sub-basin is the southwestern part of the Ib River Basin, Odisha, India. A Lower Gondwana fossil horizon was explored along the road section near Himgir Village, Sundargarh District, Odisha and plant megafossils (1002 specimens) comprising both pteridophytes and gymnosperms, four plant groups, ten genera and fifty-five species were reported. Pteridophytes (Equisetales, Sphenophyllales and Filicales) are represented by Schizoneura gondwanensis Feistmantel, 1876, equisetaceous stems, Trizygia speciosa Royle, 1839 and Neomariopteris talchirensis Maithy, 1974. Gymnosperms are represented by one plant group namely Glossopteridales (46 species Glossopteris) along with stem casts, fructifications and scale leaves. The occurrence of Late Permian floras, the lack of distinctive Dicroidium flora of the Triassic period in this assemblage, and the red bed facies (ferruginous red sandstone and ferruginous red shale) of the investigated locality reveal that the exposure belongs to Lower Kamthi Formation of Wuchiapingian to Changhsingian age. The macrofloral assemblage demonstrates a warm-humid climate with flashing rainfall and moderate light intensity. Vegetation of the studied sub-basin has also been studied to portray the palaeobiodiversity of the area.
