A squid -like creature that existed 68 million years ago and whose 1.5-metre-long shell resembled a paperclip could have had a 200-year lifespan, researchers have said. The animal, whose ...

This means that one unlucky ammonite, an ancient cephalopod that lived during the Late Jurassic period about 150 million years ago, was probably smart enough to be all too aware of its horrifying ...

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 ...

Ammonites are an extinct group of cephalopods — marine molluscs — which lived from 409–65 million years ago. They had tentacles and typically sported coiled shells, although later forms saw ...

Scientists believed that ammonites, like modern cephalopods, had soft body tissue with tentacles attached to their heads for catching prey.
