Short summary
Understanding how carbon moved through ancient environments helps reconstruct past climates and predict future trends. We compiled a global database of total organic carbon and organic carbon isotope measurements from ancient land sediments spanning 350 million years. This collection of over 66 000 data points from 619 publications provides a unified resource to study carbon accumulation on ancient continents, climate shifts, and how these changes influenced life on Earth.
