Scientists utilized 3D X-ray imaging to uncover new details that challenged previous ideas about prehistoric marine life.

Scientists scanned a fossil of the Jurassic cephalopod Vampyronassa, pictured here, and found clues that it was an active hunter. A. Lethiers, CR2P-SU Finding and studying fossils of Earth’s ...

The ancient cephalopod, Nanaimoteuthis haggarti, appears to have been an apex predator that rivaled mosasaurs to rule prehistoric seas.

Somewhere between 100 and 72 million years ago, while mosasaurs and plesiosaurs dominated the world’s oceans, something else was hunting in the deep: octopuses that may have stretched roughly 19 ...

An ancient cephalopod fossil may be about to rewrite the history of octopuses and vampire squid, but it depends on who you ask. At the very least, it’s offering up a lesson in how hard it is to ...

The word “fossil” tends to evokes calcified bones or shells — the “hard” body parts of an animal that died long ago. That’s partially because it is very rare for soft tissue — literal flesh making up ...

Researchers took 3-D printed reconstructions of fossil cephalopods to actual water tanks (including a swimming pool) to see how their shell structure may have been tied to their movement and lifestyle ...

The Jurassic cephalopod Vampyronassa rhodanica, thought to be the oldest known ancestor of the modern-day vampire squid (Vampyroteuthis infernalis), was likely an active hunter -- a mode of life that ...

Researchers have identified the earliest known relative of modern-day vampyropods. The family of creatures includes both octopuses and squid. The scientists published a study in the journal Nature ...

Mesozoic seas were full of marine monsters. There were snaggle-toothed fish, shell-crushing sharks, and, of course, enormous mosasaurs. Now, researchers have revealed another dangerous denizen of the ...
