Five hundred million years ago, the Earth saw a huge jump in the diversification of life forms called the Cambrian Explosion.

During the Cambrian, the Grand Canyon was much closer to the equator than it is today, and conditions were perfect for supporting a wide range of life.

Paleontologists named the worm Kraytdraco spectatus, for its resemblance to a Star Wars monster. They say it sheds light on the Grand Canyon’s prehistoric ecosystem.

“These rare fossils give us a fuller picture of what life was like during the Cambrian period,” said first author Giovanni Mussini, a PhD student in Cambridge’s Department of Earth Sciences.
