Second, in collaboration with David Evans and Timothy Raub at Yale University, a reevaluation of the global paleomagnetic database has revealed great circle (rather than the small circles expected for motions related to seafloor spreading and plate tectonics) distributions of poles during the interval 610-510 Ma. Could a series of inertial interchange true polar wander events have caused landscape and ocean-geochemical disequilibrium just prior to and during the Cambrian explosion?
