Eocene Magnetic Field Reversals are reshaping scientific understanding of how Earth’s magnetic shield behaves over deep time. New research based on sediment cores from the North Atlantic reveals that two geomagnetic flips during the Eocene Epoch lasted far longer than previously believed. Instead of completing within roughly 10,000 years — the long-accepted average — these…
