Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.

Discovering Fossils

A fossil is any evidence of past life preserved in a geologic context, such as within rock or sediment. This activity allows you to explore the process used by paleontologists — scientists who study fossils to understand ancient landscapes, climate, and life on Earth — to find and identify fossils.
