- 'Gigantic' ancient octopus used jaws to crush prey and hunted alongside the dinosaurs 100M years ago: study
A study by Hokkaido University researchers revealed that ancient octopuses lived 100 million years ago, coexisting with dinosaurs and reaching lengths up to 20 meters. Fossilized jaws found in Japan and Vancouver Island suggest these predators used powerful jaws to crush prey, challenging previous assumptions about marine food chains dominated by vertebrates.
- Meet the 19-meter Cretaceous kraken that swam with mosasaurs
A new study challenges the long-held belief that Cretaceous oceans were dominated solely by vertebrate predators like mosasaurs and sharks. Researchers discovered fossilized remains of giant, finned octopuses up to 19 meters long, suggesting they were apex predators with hardened beaks and high intelligence, altering the understanding of marine ecosystems 80 million years ago.
