Scientists have found the oldest known ancestor of octopuses an approximately 330m-year-old fossil unearthed in Montana.
The researchers concluded the ancient creature lived millions of years earlier than previously believed, meaning that octopuses originated before the era of dinosaurs.
The 4.7-inch (12-cm) fossil has 10 limbs modern octopuses have eight each with two rows of suckers. It probably lived in a shallow, tropical ocean bay.
Its very rare to find soft tissue fossils, except in a few places, said Mike Vecchione, a Smithsonian National Museum of Natural History zoologist who was not involved in the study. This is a very exciting finding. It pushes back the ancestry much farther than previously known.
