China-led study: 'Greater Gondwana' was 80% of Earth's crust 500m years ago

A peer-reviewed study in Science Advances, led by Chinese scientists, reports that the ancient supercontinent Gondwana was significantly larger than previously thought, comprising up to 80% of Earth's crust around 500 million years ago. The findings, based on new geological evidence, revise models of continental formation and may have implications for understanding mineral deposits and tectonic history. The claim is based on a single study and requires corroboration from the broader scientific community.
