Researchers have uncovered fossil evidence of ancient, finned octopuses that reached lengths of up to 19 meters and possessed powerful beaks. A new study argues these creatures were apex predators in oceans that also contained large sharks and mosasaurs.
Facts First
- Fossils reveal ancient octopuses with fins that likely reached lengths of up to 19 meters.
- The creatures possessed powerful, hardened beaks.
- A new paper argues they were apex predators in Cretaceous oceans.
- The oceans at that time also contained 17-meter mosasaurs, plesiosaurs, and large sharks.
What Happened
Researchers have uncovered fossilized remains of ancient, finned octopuses. The fossilized octopuses likely reached lengths of up to 19 meters and possessed powerful, hardened beaks. A new paper published in the journal Science argues that these octopuses were apex predators. Approximately 80 million years ago, during the late Cretaceous period, oceans contained 17-meter mosasaurs, long-necked plesiosaurs, and large predatory sharks.
Why this Matters to You
This discovery may reshape our understanding of prehistoric marine ecosystems, showing that cephalopods could have competed with and even dominated over the iconic giant reptiles and sharks of the era. It highlights how scientific knowledge of Earth's history is continually evolving.
What's Next
Further analysis of the fossils could reveal more details about the octopuses' anatomy and behavior. The study, co-authored by paleontologist Yasuhiro Iba of Hokkaido University, is likely to prompt new searches for similar fossils and inspire revised models of Cretaceous ocean food webs.
