- Title
A study on megafloral, palynofloral, and palynofacies of Barakar sediments at and around Balaram Opencast Coal Project, Talcher Basin, Odisha, India: inferences on palaeodepositional settings, palynodiversity, palaeovegetation, and palaeoclimate.

- Abstract
An integrated work on palynofloral and palynofacies studies along with megafloral analysis has been carried out with the samples recovered from Balaram Opencast Coal Project (N20°56′58″ latitude and E85°05′31″ longitude), Talcher Basin, Odisha, India. The analyzed samples are characterized by the dominance of degraded organic matter (39–49.5%, avg. 44.2%) and sub-dominance of palynomorphs (13.7–41.2%, avg. 27.45%). Recovered palynoassemblage along with the lithology (carbonaceous shale, dark gray shale, sandstone, silty shale, and coal seams) of the studied area explicitly depicts that the investigated sediments belong to the Barakar Formation of late Early Permian (late Artinskian to Kungurian) age. For the first time, an exclusive record of Vertebraria is made from this location, demonstrating the presence of a deciduous Glossopterids forest during the deposition of Barakar sediments. In addition, the present study also reveals a warm, humid, temperate climate with abundant rainfall during this period. The palynofacies analysis demonstrates a flooded palaeomires/marshy condition in the distal dysoxic-oxic low energy settings during late Artinskian to Kungurian.
