    • Abstract

       

      Recent investigations carried out in the Ib River Coalfield, Mahanadi Master Basin, Orissa, identified some fossiliferous beds in the Lower Gondwana deposits. Two exposures of the Lower Kamthi Formation yielded diverse and abundant plant remains, which includeNeomariopteris, Vertebraria, and a scale leaf along with 14Glossopteris species otherwise mapped as Barren Measures and Upper Kamthi formations.Glossopteris indica dominates the flora (22.78%) followed byG. communis (17.72%) andG. browniana (13.92%). Based on megafloral assemblages, different beds exposed at Gopalpur and Laxamanpur Pahar are assigned here to the Lower Kamthi Formation (Late Permian). The floristic composition suggests that a warm and humid climate prevailed during the Late Permian. The status of the Kamthi Formation in the Ib River Coalfield has been redefined in the present study.
