The ‘oldest octopus’ in the world isn’t an octopus after all, scientists find
CNN • • science
Key Points:
- A 300-million-year-old fossil previously believed to be the world's oldest octopus has been reclassified as a nautiloid, a relative of modern nautiluses, based on new research published in Proceedings of the Royal Society B.
- The fossil, Pohlsepia mazonensis, was found at Mazon Creek near Chicago and had been misidentified due to its decomposed state, which gave it an octopus-like appearance.
- Researchers used advanced techniques, including scanning electron microscopy and synchrotron imaging, to uncover hidden anatomical features, such as a radula with more teeth than an octopus, confirming its true identity.
- The study highlights the impact of modern technologies in paleontology, enabling scientists to revise long-held assumptions and deepen understanding of ancient life forms.
- Lead author Thomas Clements emphasized that paleontology is evolving into an innovative field thanks to more accessible and affordable analytical tools.
