Scientists from Northwestern have published new findings on the factors that triggered the oceanic anoxic event (OAE) 1a in the Early Cretaceous Period about120 million years ago. The unprecedented ...

The eastern North American population of monarch butterflies are famous for their annual, multi-generational, round-trip migration from the oyamel fir forests of Central Mexico through the United ...

A study by researchers at Department of Geoscience, Aarhus University, Denmark now shows that strontium isotopes may often be used incorrectly in archeological studies, as the widespread use of added ...

Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic ...

This geological map of equatorial Africa shows strontium isotope sampling locations Oelze’s team will use to create the first-ever strontium isotope map of the region, a tool researchers will use to ...

A team of researchers led by UC Santa Cruz recently released a sophisticated new map that reveals, for the first time, the unique “geologic fingerprints” for most of the African continent. The map ...

The ratios of strontium isotopes in fossil shark teeth can be used to better understand how coastal environments evolved in ancient times, according to our newly published work. Our study was one of ...
