A rich Glossopteris dominated plant fossils assemblage is recovered from the Barakar Formation of Lalmatia coal mine, Hura coalfield of Rajmahal Basin, Godda district, Jharkhand, India. The assemblage includes Glossopteris, Gangamopteris and Noeggerathiopsis (leaf forms) along with Vertebraria (root form). There are 4 genera and 14 species of megafossils in the collection, which includes 10 species of Glossopteris, two species of Gangamopteris and one species of Noeggerathiopsis and Vertebraria each. The flora, although similar to that of the Barakar Formation of the Damodar Basin complex, exhibit unique characteristics and is of Artinskian to Kungurian in age. The palynoassemblage recovered in the section reveals the dominance of genus Scheuringipollenites and sub-dominance of Faunipollenites (=Protohaploxypinus) along with Parasaccites, Potonieisporites, Barakarites, Plicatipollenites, Striomonosaccites, Striatopodocarpites, Crescentipollenites, Verticipollenites, Rhizomaspora, Distriatites, Primuspollenites, Striasulcites, Lunatisporites, Guttulapollenites, Platysaccus, Microfoveolatispora, Microbaculispora, Horriditriletes, Tiwariasporis and Weylandites, which demonstrates an early Permian age (Artinskian). The palynoassemblage indicates that the sediments belong to the lower part of the Barakar Formation. Biomarker analysis suggests varying organic matter input during the deposition of the studied sequence. Diterpane compounds and megafossil evidences suggest Glossopteris were the dominant flora along with conifers. Bacterial alteration of the organic matter is inferred from the hopane compounds. The δ13C value of organic matter associated with the carbonaceous shale directly corroborates with the typical δ13C values of the Permian time and is suggestive of warm and humid climatic conditions.

基于形态分类学、孢粉型、生物标志物和稳定同位素的古植物群研究来自贾坎德邦戈达区拉杰马哈尔下冈瓦纳盆地拉马提亚煤矿：一项包容性实证研究

从印度贾坎德邦戈达地区拉杰马哈尔盆地 Hura 煤田拉尔马提亚煤矿的巴拉卡组中发现了丰富的 Glossopteris 占主导地位的植物化石组合。该组合包括 Glossopteris、Gangamopteris 和 Noeggerathiopsis（叶型）以及 Vertebraria（根型）。馆藏巨型化石4属14种，其中舌翅目10种，甘翅目2种，Noeggerathiopsis和Vertebraria各1种。植物群虽然与达莫达尔盆地复合体的 Barakar 组相似，但表现出独特的特征，并且在年龄上属于 Artinskian 至 Kungurian。在该部分恢复的孢粉组合揭示了 Scheuringipollenites 属的优势和 Faunipollenites (= Protohaploxypinus) 与 Parasaccites 的亚优势，Potonieisporites、Barakarites、Plicatipollenites、Striomonosaccites、Striatopodocarpites、Crescentipollenites、Verticipollenites、Rhizomaspora、Distriatites、Primuspollenites、Striasulcites、Lunatisporites、Guttulapollenites、Platysaccus、Microfoveolatispori 和 孢粉组合表明沉积物属于巴拉卡组下部。生物标志物分析表明在研究序列的沉积过程中输入的有机物质会发生变化。二萜化合物和巨化石证据表明 Glossopteris 是与针叶树一起的主要植物群。从藿烷化合物推断有机物的细菌改变。
