How Fossils Form and What They Tell Us About the Past

~60 min · 15 stations

How Fossils Form and What They Tell Us About the Past is a self-paced learning path in Earth Sciences & Geography, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify primary types of fossilized biological evidence; explain the concept of deep geological time; describe conditions favoring fossil preservation.

Conductor

The Conductor

Welcome aboard this expedition through deep time. We shall explore the rocky archives that hold the secrets of life before humanity.
