Fossils and Trilobites

Beneath the Earth's crust 

A prehistoric history etched in dust

Bedrock of Cambrian rocks and fossils

Shells of Trilobites and Ammonites 

Etched in Cambrian clay and rocks 

Cambrian rocks and fossils 

Imprints of geologic time 

Where Trilobites ruled the ocean

They swam and crawled when life was new

Beneath an ocean, deep and blue

Now preserved in clay blocks

Trilobites rest within the Cambrian rocks
