Five species of gastropods and two of bivalves are being reported, and described from the mudstone horizon immediately underlying geochronologically dated (2.80.56m.y.) bentonitized tuff band exposed at Barakhetar village in a stream cutting section. The reported fauna comprises Gastropods: Gastrocopta sp., Gyraulus sp. indet., Viviparus bengalensis, Viviparus sp., Bellamya celispiralis and Bivalves: Lamellidens lewisi, Oxynaia sp. indet. Stratigraphically, the fossil (gastropod and bivalve) bearing mudstone horizon belongs to the Nagrota Formation of Upper Siwalik Subgroup of Jammu Province, Jammu and Kashmir, India and located about 30km east of Jammu city. A brief account of the age and palaeoecology of the recovered taxa have also been discussed in the present paper.
