Strontium isotope geochemistry plays a pivotal role in elucidating Earth’s dynamic processes. By utilising both stable (δ88/86Sr) and radiogenic (87Sr/86Sr) isotopic systems, researchers are able to ...

The ratios of strontium isotopes in fossil shark teeth can be used to better understand how coastal environments evolved in ...

Misha lived her whole life in zoos, but this elephant's teeth are now helping scientists reconstruct wildlife migrations. Geologists show how strontium isotopes found in teeth or tusks reveal where ...

A single tusk is all that remains of a mammoth that lived approximately 14,000 years ago. Yet that one tusk has enabled scientists to uncover remarkable details about her life. Using ancient DNA, ...
