Macro and miofloral analyses of coal-bearing sequences of the Jarangdih coal mine, Damodar Basin, were carried out to infer the floral diversity, age assessment, and the palaeoenvironment during the deposition of the Barakar Formation in this area. Damodar Basin, one of the five major Gondwana basins in India, is considered as the reference basin for inter-basinal age correlations. The Barakar strata of this colliery have yielded a diverse macroflora consisting of the groups Glossopteridales (Glossopteris, Vertebraria, Gangamopteris, fructifications, and stem casts) and Equisetales (Phyllotheca indica, Schizoneura gondwanensis, and Paracalamites sp.). The genus Glossopteris dominates the assemblage with 16 species viz. G. arberi, G. communis, G. churiensis, G. giridihensis, G. indica, G. intermedia, G. intermittens, G. leptoneura, G. linearis, G. mohudaensis, G. recurva, G. searsolensis, G. stenoneura, G. taenensis, G. tenuifolia, and G. tenuinervis. The leaves of Glossopteris leptoneura have impressions of male sporangia adhered on them. The groups Lycopodiales, Coniferales, Sphenophyllales, and Filicales are not represented as macrofloral remains; however, their presence is recorded in the palynoassemblage.The palynological analysis has revealed only one palynoassemblage characterised by the dominance of striate bisaccate palynomorphs mainly Faunipollenites and non-striate bisaccate pollen—Scheuringipollenites. The other stratigraphically significant palynotaxa are Striatopodocarpites, Verticipollenites, Crescentipollenites, Striatites, and Arcuatipollenites. The recovered palyno- and megafloral assemblages suggest the late early Permian (Kungurian) age to the Barakar strata of Jarangdih coal mine and prevalence of moderately warm climate during their deposition.

二叠纪早期的花卉多样性与环境：以印度达莫达盆地东博卡罗煤田的Jarangdih煤矿为例

进行了Damodar盆地Jarangdih煤矿含煤序列的宏观和花期分析，以推断该地区Barakar组沉积期间的花艺多样性，年龄评估和古环境。Damodar盆地是印度的五个主要冈瓦纳盆地之一，被认为是基准年龄之间相关性的参考盆地。这个煤矿的Barakar阶层已经产生了由组舌羊齿目的多样化macroflora（舌羊齿，Vertebraria，Gangamopteris，fructifications和干管型）和Equisetales（Phyllotheca籼稻，Schizoneura gondwanensis和Paracalamites SP）。属Glossopteris以16种物种占主导地位。摹。arberi，G. communis，G. churiensis，G. giridihensis，G. indica，G. intermedia，G. intermittens，G. leptoneura，G. linearis，G. mohudaensis，G. recurva，G. searsolensis，G. stenoneura，G. taenensis，G.细叶和G. tenuinervis。Glossopteris leptoneura的叶子对他们有男性孢子囊的印象。Lycopodiales，Coniferales，Sphenophyllales和Filicales组不代表为大花遗骸；孢粉学分析表明，只有一种以特征为双方酸盐的条纹状双孢粉状形态，主要是Faunipollenites和非纹状的双刃状花粉-Scheuringipollenites为主的孢粉组合。其他地层显著palynotaxa是Striatopodocarpites，Verticipollenites，Crescentipollenites，Striatites和Arcuatipollenites。恢复的古植​​物和大植物组合表明，二叠纪（Kungurian）时代早于Jarangdih煤矿的Barakar地层，沉积期间普遍存在中度温暖的气候。
