Scientists Find 60-Foot 'Kraken' Octopus From 100M Years Ago

The mythical Kraken never existed, but scientists just found something remarkably close to it lurking in the fossil record.

Researchers discovered jaw fossils from a massive octopus called Nanaimoteuthis that lived 100 million years ago, according to research published in Science. This ancient creature stretched up to 60 feet long, making it as large as some of the biggest marine reptiles of its time.

Finding octopus fossils is incredibly rare because these soft-bodied animals usually decompose completely after death. Only their hard jaws survive millions of years, giving scientists tiny windows into their ancient world.

The jaw fossils tell a powerful story. They show heavy wear and tear, including chips and scratches consistent with crushing shells and even pulverizing bones. This octopus wasn't just surviving. It was hunting large, tough prey and sitting near the top of its food chain.

Scientists used a combination of traditional fossil analysis and cutting-edge "digital fossil mining" technology to identify the creature. This technique scans rock layers at high resolution to peek inside without damaging the specimens.

Why This Inspires

This discovery rewrites our understanding of who ruled the ancient seas. For years, scientists assumed vertebrates like plesiosaurs, mosasaurs, and gigantic sharks dominated the late Cretaceous oceans. These massive predators seemed unstoppable.

But this giant octopus proves that invertebrates could compete at the highest levels too. Intelligence, adaptability, and strength came in more forms than we imagined.

Modern octopuses are already among the ocean's most intelligent creatures, solving puzzles and adapting to countless environments. Discovering their ancestors were apex predators 100 million years ago adds a remarkable chapter to their evolutionary story.

The finding reminds us how much we still don't know about our planet's history. Every new fossil opens doors to understanding how life thrived, adapted, and dominated in ways we never expected.

Those ancient Norse storytellers imagined a giant octopus terrorizing the seas, and now we know they weren't entirely wrong about such creatures existing. They just got the timeline off by about 100 million years.
