“…Enlargement of Barakarella sp. The palynoassemblage recorded in the present study, is comparable with the early Permian palynoassemblages of Korba (Bharadwaj & Srivastava, 1973), Johilla (Anand-Prakash & Srivastava, 1984) and Umaria (Srivastava & Anand-Prakash, 1984) coalfields of South Rewa Gondwana Basin; Umrer Quarry, Nagpur (Bharadwaj & Anand-Prakash, 1974), Wardha Coalfield (Bhattacharyya, 1997) and Umrer Coalfield (Jha et al, 2007) of Wardha Basin, Shobhapur block, Pathakhera Coalfield (Srivastava & Sarate, 1989) of Satpura Gondwana Basin; and Manuguru (Srivastava & Jha, 1992), Mamakannu (Jha & Aggarwal, 2010), Gundala (Jha & Aggarwal, 2011), Mailaram (Jha & Aggarwal, 2012) and Lingala-Koyagudem (Aggarwal & Jha, 2013) areas of Godavari Graben. Besides, it shows resemblance with the upper Karharbari palynoassemblage of the Damodar Basin.…”

Well preserved palynomorphs from the Barakar Formation of Dhanpuri Open Cast Mine, Sohagpur Coalfield, Shahdol District, Madhya Pradesh are reported for the first time. The palynomorphs include megaspores and spores/pollen grains. Dispersed megaspores are represented by 6 genera and 13 species comprising Banksisporites indicus, B. utkalensis, Banksisporites sp., Barakarella shuklae, Barakarella sp., Biharisporites sp. Bokarosporites rotundus, Bokarosporites sp., Jhariatriletes baculosus, Jhariatriletes sp., Talchirella flavata, T. trivedii and Talchirella sp. The microspore assemblage shows dominance of monosaccate pollen grains namely Parasaccites obscures, P. korbaensis and Plicatipollenites indicus, along with sub–dominance of non–striate bisaccate taxa Scheuringipollenites barakarensis and S. maximus. Other palynomorphs include trilete Callumispora barakarensis, striate bisaccate pollen grains Faunipollenites sp. and Striatopodocarpites multistriatus, non striate bisaccate genera Ibisporites diplosaccus and Platysaccus ovatus, along with Tiwariasporis gondwanensis and Vitreisporites sp.

“…Assemblage A of the Tamia Ghat Section, (Kumar, 1996) and Pench Valley Coalfield (Murthy et al, 2013). The present assemblage can also be correlated with the latest Permian palynoassemblages known from the different areas/coalfields of Wardha-Godavari Basin such as Kamptee (Srivastava & Bhattacharyya, 1996); Manuguru (Srivastava & Jha, 1992); Sattupalli (Srivastava & Jha, 1994); Budharam (Srivastava & Jha, 1995); Bottapagudem (Jha, 2004); Gundala (Jha & Aggarwal, 2010); Mailaram (Jha & Aggarwal, 2012); Lingala-Koyagudem (Aggarwal & Jha, 2013) and Chintalapudi sub-basin (Jha et al, 2014) showing dominance of striate bisaccate pollen grains along with Densipollenites sp. However, Guttullapollenites has not been recorded in the present assemblage.…”

A 1300 m thick sedimentary sequence in borehole SNB–1 around Jaisinghnagar area in the western part of the South Rewa Basin has been lithologically designated as the Pali Formation. However, palynological investigation reveals presence of three distinct palynoassemblage zones belonging to late Permian, early and late Triassic ages in ascending order. Palynoassemblage I (Striatopodocarpites magnificus–Crescentipollenites fuscus) recorded between a depth of 1213.40–1164.10 m showing dominance of striate bisaccate pollen taxa chiefly―Striatopodocarpites ovatus, Faunipollenites varius and Crescentipollenites fuscus in association with Alisporites ovalis, Lunatisporites pellucidus, Densipollenites indicus and Lahirites rarus is late Permian (Raniganj) in age. Palynoassemblage II (Lundbladispora densispinosa–Densoisporites playfordii) recorded between a depth of 1054.30–956.00 m and showing dominance of cavate/cingulate spores, like Lundbladispora microconata, Densoisporites complicatus along with Kraeuselisporites rallus, Lapposisporites lapposus, Playfordiaspora crenulata, Goubinispora indica, Klausipollenites schaubergeri, Limatulasporites fossulatus and Reduviasporonites chalastus indicates an early Triassic age. Palynoassemblage III (Aulisporites astigmosus–Falcisporites nuthallensis) recorded between a depth of 404.40–53.60 m and characterized by the dominance of Aulisporites astigmosus along with Falcisporites nuthallensis, Tikisporites balmei, Dubrajisporites unicus, Enzonalasporites densus, Leschikisporites aduncus, Lunatisporites rhaeticus, Lueckisporites virkkiae, Playfordiaspora vellata, Polycingulatisporites crenulatus, Cingulizonates indicus, Neoraistrickia taylori and Aratrisporites fischeri is equated with late Triassic (Supra–Panchet) age. The Permian–Triassic boundary is delineated at the contact of coal/shale bearing upper part of the Middle Member and lower part of the Upper Member of the Pali Formation (between 1164.10–1075.15 m depth). At the P/T boundary, the abrupt change of the palynoflora is marked by the disappearance of the striate bisaccate pollen grains and appearance of non–striate bisaccate grains in association with cingulate–cavate/zonate trilete spores. The Permian/Triassic palynofloras recorded in South Rewa Basin show close similarities with those of the uppermost Bainmedart Coal Measures (McKinnon Member) and Flagstone Bench Formation of east Antarctica.

“…The Parasaccites dominated palynoflora in association with other monosaccate genera, namely-Plicatipollenites, Caheniasaccites, Pachysaccus and Crucisaccites along with poor representation of nonstriate bisaccate pollen, is comparable with Upper Karharbari palynoflora of Damodar Basin (Srivastava, 1973;Bharadwaj, 1974); Godavari Basin (Srivastava & Jha, 1995;Jha & Sarate, 2001;Jha & Aggarwal, 2010) and Satpura Basin (Srivastava & Sarate, 1989). The present record of palynoassemblage shows the dominance of high percentage of Parasaccites while trilete and striate bisaccate taxa are low.…”

The present paper deals with mega- and microfossils recovered from the Early Permian sediments of the Johilla-Ganjra Nala confluence of Johilla Coalfield, Madhya Pradesh. Megafossils include Gangamopteris major, G. cyclopteroides, Glossopteris indica, G. gigas, G. conspicua, G. mohudaensis, Noeggerathiopsis hislopii, Samaropsis goraiensis, Cordaicarpus zeilleri, Alatocarpus indicus, few platyspermic seeds and Equisetalean axes. The palynological studies reveal that coal-bearing beds contain dominance of monosaccate pollen (Parasaccites, Plicatipollenites and Pachysaccus) in association with Callumispora gretensis, Crucisaccites monoletus, Barakarites indicus, Faunipollenites varius, Lunatisporites diffusus and Crescentipollenites fuscus indicating an Early Permian age to the coal beds exposed near the confluence of Johilla River and Ganjra Nala. The mega- and microflora recorded from these beds indicate a transitional zone of the Upper Karharbari and Lower Barakar formations. The study further suggests that the climatic conditions of Son Valley were cooler than the Damodar Basin.
