Life reconstruction of Mosura fentoni. Photo released May 13 2025. A "remarkable" three-eyed predator nicknamed the "sea-moth" that lived 506 million years ago has been identified.The fossilised remains of the unusual creature, called Mosura fentoni, were discovered by palaeontologists in the Burgess Shale fossil-bearing deposit in the Canadian Rockies.The Canadian team say it was about the size of a human index finger and had three eyes, spiny jointed claws, and a circular mouth lined with teeth as well as a body with swimming flaps along its sides. Those traits show it to be part of an extinct group known as the radiodonts, according to findings published in the journal Royal Society Open Science.
