Discovery of 'Cretaceous Kraken' Fossils Reveals Ancient Apex Predator
Recent research has uncovered fossils of a giant octopus species, Nanaimoteuthis haggarti, which lived during the Cretaceous Period, approximately 86 to 72 million years ago. These fossils, found in Japan and Canada, suggest that this species could grow up to 61 feet long, challenging the previous understanding that ancient oceans were dominated solely by large vertebrate predators. The study, led by paleontologist Yasuhiro Iba of Hokkaido University, indicates that these octopuses were apex predators, competing with marine reptiles and sharks for dominance in their ecosystems.
