Science just got wild, and we’re here for it. Imagine a 500-million-year-old marine creature that looks like nature’s most terrifying adult toy, complete with multiple razor-sharp tooth rings.

Researchers recently uncovered a fossil of an ancient penis worm in the Grand Canyon that’s basically the nightmare fuel of marine biology. Named Kraytdraco spectatus (yes, inspired by Star Wars), this prehistoric predator would make modern marine life look like absolute amateurs.

Teeth for Days

This bad boy measured about 15 to 20 centimeters long - which is massive compared to today’s microscopic penis worms that max out at 2-3 millimeters. Scientists hypothesize it had a retractable throat lined with concentric tooth rings, basically functioning like a Swiss Army knife of marine consumption.

Ancient Eating Machinery

The worm likely had a two-stage eating process: sharp teeth to grab food like algae and microorganisms, and more delicate feathered teeth to filter and chew its catch. It’s essentially the Gordon Ramsay of prehistoric marine cuisine - precise, aggressive, and absolutely uncompromising.

Time Traveling Predator

Discovered during an expedition along the Colorado River, this fossil comes from an era before the Cambrian period - considered the dawn of complex animal life. The find doesn’t just tell us about one weird worm; it gives us a glimpse into the earliest predators that roamed our planet’s oceans.

Who said paleontology was boring? Not us. This penis worm just entered the chat, and we’re taking notes.
