A striking feature of the geomagnetic time scale is the approximately 34 m.y. period of normal polarity field bias known as the Cretaceous Normal Polarity Superchron. New paleomagnetic data from three Deep Sea Drilling Project cores (Sites 317A, 402A, and 463) indicate that a brief interval of reversed polarity occurred during the Superchron. This reversed polarity interval may help refine past motions of the Pacific plate and aid resolution of the statistical structure of the geomagnetic reversal chronology.
