A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

Geophysical Research Letters
The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior.

Enhanced phosphorus regeneration linked to Ediacaran ocean oxygenation

Communications Earth & Environment
Several pulses of ocean oxygenation events were recognized in the Ediacaran period. However, the intrinsic triggers behind them remain ambiguous. Here we report phosphorus speciation data from the Ediacaran Doushantuo Formation, South China, to elucidate
