Meet Cambroraster falcatus, a hand-size predator that lived about half a billion years ago, during the Cambrian period. It looked so much like the Millennium Falcon from "Star Wars" that paleontologists named the species after the spaceship. [Read more about the fearsome Cambrian predator]
C. falcatus had a shell on its head called a carapace. The deep notches are where the creature's eyes would have sat.
Jean-Bernard Caron, a curator of invertebrate palaeontology at the Royal Ontario Museum in Canada, excavated a C. falcatus fossil. All of the fossils were found in the famous Burgess Shale deposit in the Canadian Rockies.
Most of the fossils show that the creature was about the size of a person's hand. The largest individual was nearly 12 inches (30 centimeters) across, Caron told Live Science.
These fossils show both sides of the first complete specimen that scientists found.
C. falcatus had rack-like claws that it likely used to catch prey.
The predator's mouth looked like a circular pineapple slice. Notice the rows of toothed plates.
Small but deadly
This helps put the size of C. falcatus in perspective.
One of many
The paleontologists found 140 unique fossils of C. falcatus in the Canadian Rockies.
This map shows the approximate locations of Marble Canyon and Tokumm Creek, where the fossils were discovered in the Canadian Rockies.
