Ammonites were shelled cephalopods that died out about 66 million years ago. Fossils of them are found all around the world, sometimes in very large concentrations. The often tightly wound shells of ...

Ammonites are extinct marine mollusks that ... They were spiral-shelled creatures, closely related to modern cephalopods like squid and octopuses. In fact, they emerged over 100 million years ...

Some extinct species left copious fossil remnants of their existence. Ammonites—an extinct type of cephalopod—are one such example. From the Devonian right up until the Paleocene, wherever ...

This maneuverability may have helped them catch prey or avoid slow predators (like other shelled cephalopods). Peterman notes that some interpretations consider many ammonite shells as ...

We now know ammonites are extinct cephalopod molluscs related to squids and octopuses, which lived in the seas of the Mesozoic Era between about 201 and 66 million years ago. Their shells are ...

Studies of ammonite evolution and paleoecology thus ... In a recent biomimetic study, researchers utilised 3D-printed cephalopod models to experimentally validate the trade-off between ...

Ammonites belonged to the cephalopod group of marine invertebrates, current members of which include octopi, squid and cuttlefish. Unlike those examples, however, ammonites had protective outer ...
