Glossary Category: Fossil Localities

Fossil localities are geographically defined sites or stratigraphic units where fossils are found and scientifically documented. These locations preserve evidence of ancient ecosystems, climates, and evolutionary transitions. From river deposits to marine basins, fossil localities provide critical context for understanding how organisms lived, interacted, and became preserved in the rock record.

This category explores major fossil-producing formations worldwide, emphasizing geological age, depositional environment, and scientific significance.
