The results of a high resolution bedrock controlled sampling of Mud, Guling and Lalung in the Spiti District, India are presented. These areas yielded abundant and rather well preserved Dienerian ammonoids, which compare well with the revised ammonoid successions from the Salt Range (Pakistan). The Dienerian ammonoid faunas from both regions are remarkably similar and the new threefold subdivision of the Dienerian (early, middle and late) proposed in the Salt Range also applies to Spiti. Moreover, 10 out of the 12 Dienerian regional zones defined in the Salt Range are rec-ognized in Spiti, with the same associations of characteristic species. Thus the initial biostratigraphical scheme established in the Salt Range can be reproduced laterally and is valid throughout most of the Northern Indian Margin. The four new species Gyro-nites levilatus, Gyronites bullatus, Ambites nyingmai and Vavilovites meridialis are introduced.
