A survey of trace fossi1s in cores of Kopili. Barail and Tipam (TS-5 member) sequences from Upper Assam Shelf reveals that the burrow types occurring in the sediments, produced by suspension and deposit feeding animals, includes Skolithos, Thalassinoides, Planolites and ?Muensteria. These ichnogenera indicate Skolithos ichnofacies and suggest that cores of Kopili and Barail sequences represent deposits of moderate to high energy marine conditions.
