| Summary: | Understanding the timing and synchronicity of environmental and faunal changes at both low and high latitude successions in the Triassic can be improved by better inter-calibration of stratigraphic tools. This is all the more important for tools which potentially provide means for high resolution intersection correlation, such as those often required for defining the primary means of correlation in GSSP definitions. In this spirit an integrated biostratigraphic and magnetostratigraphic study of the latest Early Triassic to the upper parts of the Middle Triassic, at Milne Edwardsfjellet (central Spitsbergen), allows a detailed correlation of Boreal and Tethyan biostratigraphies. This is primarily achieved by linking the magnetostratigraphic patterns, from the new magnetostratigraphic data described here, to existing published magneto-biostratigraphy from Tethyan sections with conodont biostratigraphies (Muttoni et al., 1998, 2000, 2004; Nawrocki and Szulc, 2000). The biostratigraphy from Milne Edwardsfjellet consists of am- |
