Trilobites can be found in both rocky places and marine areas on Earth, even though they are marine animals. How can we use trilobites fossils to show that changes have occurred over time?

• Trilobite fossils are in both rocky and marine areas proving that Earth has changed by natural processes.

• Trilobites actually show that nothing ever changes

• Natural processes no longer occur so trilobites show nothing

• Trilobites are compressed so much by natural processes that they only show in marine places
