Trace fossils are the fossilized marks or imprints of the activities and movements of organisms that lived in the past. These fossils include footprints, trails, nests, and eggs. Trace fossils help biologists to infer characteristics of past organisms, such as their weight, speed, and gait. These fossils can also indicate behaviors, such as whether an organism traveled alone or in a group.
After completing this module, you will be able to:
Define trace fossils.
List examples of trace fossils.
Infer from trace fossils the characteristics and behaviors of animals that lived in the past.
