Summary. A rare and typically Lower Riphean stromatolite Plicatina is reported from the Indian subcontinent for the first time. Elsewhere, its only well-known report is from the Lower Riphean rocks of Morocco. The present form has been identified as Plicatina misrai, a new form-species. It occurs in the thick calcareous Kapkot Formation, which is a practically unfossiliferous and widespread rock unit of the Lesser Himalaya. The present report has wider implications in many aspects, especially in raising the level of confidence in assigning a definite age to the rock unit in which it occurs.
