“…Singh and Chandra (1995) recorded preserved Vertebraria axis from the pinkish-grain shales of Barakar Formation exposed near Brajra Nagar Railway Station. Senotheca murulidihensis, a glossopteridae fructification was discovered from carbonaceous shales of Lakura Colliery by Singh and Chandra (1989). Singh and Chandra (1999) reconstructed a fern plant Neomariopteris hughesii based on specimen collected from the Barakar Formation.…”

The sub-surface samples for the present study were collected from the Bore-Core No. IBK-A2 which was drilled at south-west part (Kuraloi block) of Ib-River Coalfield, Jharsuguda District, Odisha. Two Palynoassemblages have been identified in the 529.18 m deep bore core. The Palynoassemblage-I showing dominance of Faunipollenites - Striatopodocarpites, followed by Scheuringipollenites, Cyclogranisporites, Cyclobaculisporites, Rhizomaspora, Microbaculispora, Striatites, Alisporites, Ibisporites, Falcisporites, etc. belongs to upper Barakar Palynoflora (Late Early Permian). Palynoassemblage-II having the dominance of Striatopodocarpites and sub-dominance of Faunipollenites followed by Verticipollenites, Crescentipollenites, Rhizomaspora, Striatites, Alisporites, Densipollenites, Distriatites, Striamonosaccites, Scheuringipollenites, Striapollenites, Ephedripites, Callumispora, Cyclogranisporites, Cyclobaculisporites, Ibisporites, Parasaccites, etc. belongs to Raniganj Palynoflora (Late Permian). The dominance of striated disaccates and sub-dominance of non-striated palynoflora along with enormous distribution of triletes and taeniate spores, such as Densoisporites, Lundbladispora and Arcuatipollenites shows Late Permian (Raniganj) affinity.
