| Abstract: | This monograph analyzes all available data on the biostratigraphic and biogeographical distribution of Permian ammonoids and the ecological interpretation of morphological changes in this group. Ammonoid assemblages of various regions at successive stages of the Permian are examined. Four major stages are substantiated in the evolution of Permian ammonoids. The most contentious stages in the Permian evolution of the group are extensively discussed. |
