Trilobites are extinct animals that lived in the sea and oceans. Fossils of these animals can be found in dry areas such as Alberta. What does this indicate?
Trilobites now live underground.
Trilobites are the ancestors of jellyfish.
Alberta was once covered by an ancient inland sea where Trilobites lived.
The environment changed, and Trilobites evolved to walk on land and become amphibians.
