Index Fossils

Index fossils are fossils that are used as indicators of the age of rocks or any geologic strata in which they are found. They are typically distinctive and easily recognizable types of ancient organisms or events that occurred in a specific geological period. Due to their unique and identifying nature, they can be used to understand and infer the age of geological formations, as well as provide important information on the environment, climate and ecology of the time. Index fossils are invaluable tools for researchers when studying the ages of rocks and fossils, and have been used to create and verify different geological time scales.
