A new species of ‘penis worm’ was discovered in the Grand Canyon

It’s among a trove of fossils found in what may have been a cradle of Cambrian evolution

This new species of predatory ‘penis worm’ with a retractable mouth would have lived roughly 500 million years ago during the Cambrian Period, in a shallow sea environment. Dubbed Kraytdraco spectatus, the worm may have used an invertible, toothy throat, seen in this animation, to trap and consume small organisms and organic debris.
