The Upper Jurassic deposits of Milne Land lie in a key area for Jurassic Boreal ammonite stratigraphy. Early collections brought back to Copenhagen by Rosenkrantz (1929) and Aldinger (1935) were described in two classical monographs by Spath (1935, 1936), and all these works continue to form the basis for subsequent stratigraphical and palaeontological revisions. Since then extensive field work and collecting have yielded important new material and much more detailed stratigraphical information (Callomon, 1961; Hikansson et al., 1971; Birkelund et al., 1978a; Higgins & Hikansson, 1980; Birkelund, Callomon & Fiirsich, 1984). The biostratigraphy of the ammonites in particular has revealed a rich succession that can be used to provide.
