The highly fossiliferous succession of Smithian (Early Triassic) ammonoids from northwestern Guangxi (South China) provides a key equatorial record, at the boundary between Tethys and Panthalassa. After the end-Permian extinction, ammonoids reached their first major diversity peak during Smithian times, coupled with a marked contrast in their latitudinal distribution. This monograph contains a part of the fundamental taxonomic and biostratigraphic data of a more comprehensive research project addressing patterns of recovery in time and space of Early Triassic ammonoids and other marine clades, in conjunction with global paleoceanographic and paleoclimatic changes.

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.
