Palynological investigation has been undertaken with tile subsurface Cenozoic sediments of Ganga basin to establish biostraligraphy and environment of deposition. Samples from four bore holes viz. Puranpur, Matera, Gandak and Raxaul under study have yieldcd palynomorphs and other microfossils. Palynoassemblage recovered from the older Cenozoic sedimcnts of thc four bore holes has becn analyzed in this paper to ascertain the age and environment of deposition. Rich palynoasscmblage recovered i'rorn the Ganga basin sediments compare closely with the palynoassemblage recovered from Palcoccne-Eocene sediments of other Tertiary basins in India. Occurrence of triporate 'Normapolles' type pollen grains in the assemblage is additional significant record. The palynoassemblage suggests a predominantly tropical warm humid climate with coastal brackish water influence. In addition, reworked microfossils of early and late Paleozoic, Mesozoic ages have becn recovered in the lower Tertiary palynoassemblage.Keywords

Carbonised fruits resembling the modern taxon, Elaeocarpus lanceaefolius Roxb. of Family Elaeocarpaceae are reported for the first time in India from Siwalik sediments of Arunachal Pradesh. A new fossil species, Elaeocarpus prelanceaefolius sp. nov. is proposed for the fruits. Occurrence of these fruits indicates a sub-tropical to temperate, broad-leaved to evergreen forest in the area at the time of deposition.Full Text

In the Indian wetland palaeoecosystem, no dragonfly has been reported from the Cenozoic sediments until now. Here, we report a well-preserved fossil dragonfly (Odonata: Anisoptera) recovered from the late Neogene sediments of the Chotanagpur plateau, Jharkhand, eastern India. It is characterized by well-preserved head, thorax and a long cylindrical abdomen with terminalia and four wings with longitudinal veins, cross-veins and characteristic small pterostigma at the apex. These significant morphological attributes reveal a close resemblance of the fossil specimen with modern dragonflies of the family Libellulidae (order: Odonata, sub-order: Anisoptera). To the best of our knowledge, there is no reliable occurrence of dragonfly in the Indian fossil record. The core distribution of the dragonfly, suggests that it thrived under a tropical, warm, humid climate during the depositional period. The fossil specimen was found associated with prolific and diversified tropical angiospermic plant remains, vertebrates and invertebrates that provided a suitable palaeoniche for the dragonfly to survive. In addition, the fossil material and associated angiospermic flora indicate the terrestrial as well as freshwater lacustrine environment in Chotanagpur plateau during the depositional period.Keywords

A compressed fossil fish bearing close resemblance to sub-family Leuciscinae (family: Cyprinidae) is reported from latest Neogene (?Pliocene) sediments of Chotanagpur plateau, eastern India. The recovered fossil fish contains exceptionally well-preserved skeleton. It is characterized by compressed belly, medium-sized head, well-preserved skull, ten caudal vertebrae, moderately long vertebral spines, cycloid scales, and wellpreserved dorsal, pectoral, pelvic, anal and caudal fins. The fossil material and associated angiospermic flora indicate the existence of Leuciscinae and freshwater lacustrine environment (with intermittent fluvial incursions during flood events) in the Chotanagpur plateau during the depositional period.Keywords
