Recent research has uncovered that ancient octopuses, living between 100 and 72 million years ago during the Late Cretaceous period, might have been the largest and most intelligent marine predators of their time. These findings challenge the long-held belief that large vertebrates like sharks and marine reptiles dominated the ocean’s top predator roles. Fossil jaws of these giant octopuses, dubbed “krakens,” suggest they could reach lengths of up to 18.6 meters, surpassing even the largest known vertebrates of their era. The study, led by Shin Ikegami from Hokkaido University, analyzed wear patterns on the fossilized jaws to determine that these octopuses were carnivorous, capable of crushing the shells and bones of their prey. This discovery not only reshapes our understanding of marine ecosystems in the Cretaceous period but also provides insights into the evolution of size and intelligence in oceanic creatures.
