PDF File Journal of Geological Education: Mammals and Magnetostratigraphy. Magnetic polarity stratigraphy has become one of the most important tools for correlation oi lossiliferous terrestrial deposits. Since 1975. many of the suitable fcssilifercus ter- restrial vertebrate-bearing sequences in North America. Eurasia, South America. and Africa, have been correlated with the magnetic polarity timescale. These correlations have not only improved our understanding of the temporal sequence of vertebrate evolution, but have also been used to test the synchroneity of biostratigraphic events and the timing of migrations, and to calibrate rates of evolution and sedimentation.
