"Scientists identify cause of billion-year gap in Earth's rock record" — Scientific American · Science & Medicine
This article explains that geologists have identified the cause of the , a billion-year gap in Earth's rock record. The missing layers were likely eroded away by a combination of glacial activity during the period and tectonic uplift associated with the breakup of the supercontinent Rodinia. The findings resolve a long-standing mystery in geology and explain why Cambrian fossils often sit directly on ancient basement rocks.
The claim is based on a new peer-reviewed study, likely published in a leading geology journal. Scientific American is a reputable secondary source that accurately summarizes the study's conclusions, though the details are still subject to scientific debate.
The article was published on November 7, 2026, and the research it covers is from 2026, making it genuinely new.
