It's April 25.

I'm Kori with the story.

Researchers has dropped evidence of colossal octopuses from 100 million years ago in the

Lake Cretaceous period.

These beasts could stretch up to 60 feet long, bigger than a school bus, making them the

largest invertebrates ever found.

They proud oceans alongside mosa sores and huge sharks as top predators.

The fossils came from northern Japan, hidden inside ancient seafloor rocks, called

concretions.

A team led by paleontologists, Yasuhiro Iba, sliced them thin, imaged the insides, and

built three-dimensional models with AI help.

With the uncovered, we're tough octopus jaws, the only hard parts that survive from

the soft-bodied giants.

Scientists are blown away because octopuses rarely fossilize well with our bones.

One expert called it proof of massive octopuses we never expected.

The lead author says it highlights how unique these creatures have been evolving for ages.

From the jaws, they figured out the size and diet.

These octopuses chomped, shrimp, lobsters, and other crunchy prey, tearing it apart with

strong arms.

Scratches showed heavy wear, especially on one side, hinting at early smarts like modern

octopuses.

This paints a wild picture of Cretaceous seas, packed with giant hunters.

These shows intelligence and predatory skills ran deep in octopus history, reshaping how

we see ancient oceans.
