“new fossil evidence reveals that massive “kraken”-like cephalopods ruled the seas during the Cretaceous period, possibly preying on massive sea reptiles and other so-called apex predators, per a study published Thursday in the American Association for the Advancement of Science.”
CORROBORATED
Multiple web search results reference research suggesting 'kraken-like' octopuses from the Cretaceous period were apex predators, citing studies published in scientific journals. The claim is supported by multiple independent web search results discussing this specific paleontological finding.

“Indeed, at 62-feet-long, this colossal octopus could grow up to six feet longer than the mighty mosasaur, a predatory marine reptile that has long been considered the oceanic alpha-dog in the late Cretaceous between 100 and 60 million years ago.”
CORROBORATED
Two separate web search results corroborate the claim that the octopus could reach 62 feet and that this size was comparable to or exceeded that of the mosasaur in the late Cretaceous period, positioning it as a top predator.
