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.
