Special Papers in Palaeontology, Smithian (Early Triassic) ammonoids from the Salt Range (Pakistan) and Spiti (India)

This volume comprises 2 substantial papers that describe the Early Triassic (Smithian) ammonoids from the Salt Range (Pakistan) and the Spiti region of India.  Ammonoids are abundant and well-preserved at many localities in these regions, and their highly resolved evolutionary succession is the key to stratigraphic correlation between the 2 areas, and with other Tethyan sequences such as those in southern Tibet and south China.  Many new key genera and species are described.
