Neil D. Opdyke is Distinguished Professor Emeritus in the Department of Geological Sciences at the University of Florida in Gainesville, Florida, USA. He was previously with Lamont-Doherty Geological Observatory of Columbia University, including a stint as Director. He is well known for his groundbreaking research in the 1950s on paleoclimate and continental drift, with Keith Runcorn, and later in Africa and Australia with Mike McElhinny[1] and others. Back the US in the mid-1960s he worked on the documentation of magnetic reversals in deep-sea sediments, which led to proof of the Vine–Matthews–Morley hypothesis the governing paradigm for marine magnetic anomalies.

In 1969, Dr. Opdyke & Ken Henry used marine core data for a convincing test of the GAD hypothesis that is central to the use of paleomagnetism in continental reconstruction. Opdyke’s work with Nick Shackleton in 1973 marked the beginning of the integration of oxygen isotope stratigraphy and magnetostratigraphy that has led to current methods of tuning timescales. Neil pioneered magnetic stratigraphy in terrestrial (non-marine) sediments and produced some of the most impressive records, notably from Pakistan and southwestern USA. These studies led to a vastly improved time frame for vertebrate evolution and allowed the documentation of mammal migration.
