520 ▼a There is a growing body of evidence that the evolving redox structure of the oceans has been an important influence on the evolutionary trajectory of animals. However, current understanding of connections between marine redox conditions and mari
520 ▼a The recent development of U isotopes (delta238U) in carbonates as a global ocean redox proxy has provided new insight into this problem. Reliable application and interpretation of the delta238 238U paleoproxy in geological records requires a tho
520 ▼a To improve understanding of the role of marine redox in shaping the evolutionary trajectory of animals, high-resolution delta238238U records were generated across several key evolutionary periods, including the Ediacaran-to-Early Cambrian Explos
