Paleontologists discover a 500-million-year-old, 3-eyed predator

Paleontologists have uncovered a 500-million-year-old fossilized creature with three eyes and a mouth shaped like a pencil sharpener, known as "Mosura fentoni." Found in the Burgess Shale of the Canadian Rockies, this "sea moth" has a finger-like body length, circular mouth with teeth, and flaps for swimming, alongside 16 body segments similar to arthropods. This discovery highlights its complexity, suggesting it evolved advanced adaptations like specialized body parts, contributing to Earth's early animal diversity during the Cambrian period.
