Giant kraken-like octopus discovered

The discovery of the 'kraken' octopus challenges previous understandings of prehistoric marine ecosystems, where invertebrates were thought to play a minor role.

Researchers used novel techniques to analyze fossilized beaks found in the Gulf of Alaska, revealing a creature as large as a school bus.

These intelligent predators likely rivaled mosasaurs for dominance in the ancient seas 100 million years ago.

The find highlights the incredible diversity of life that existed during the Cretaceous period.
