Scientists say they have discovered the oldest known ancestor of octopuses: an approximately 330 million-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. “It's 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."
For decades, the fossil sat overlooked in a drawer while scientists studied fossil sharks and other finds from the site. But then paleontologists noticed the 10 tiny limbs encased in limestone.
