Using state-of-the-art imaging techniques, palaeontologists have been examining extinct marine creatures. Quantitative analyses provide new evidence that ammonites were able to swim using their shell ...

Researchers have revealed the soft tissues of a 165-million-year-old ammonite fossil using 3D imaging. They found that the now-extinct molluscs sported hyponomes: tube-like syphons through which water ...

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 shells ...

The bizarre fossil is one of very few records of soft tissue in a creature better known as a whorled shell. By Sabrina Imbler If anxious humans have nightmares of being naked in public, an anxious ...

An oddly shaped fossil in Hokkaido turned out to be a new species of ammonite, spiral-shaped marine creatures from ancient times, researchers said. The newly identified ammonite, classified as a ...

The origins of vivid colors within the gemstone ammolite—a rare type of brightly colored fossilized ammonite shell—are ...

They found that the now-extinct molluscs sported hyponomes: tube-like syphons through which water is expelled to jet propel animals forward in water, as found in modern squid and octopuses. They also ...

Using state-of-the-art imaging techniques, palaeontologists at the Ruhr-Universität Bochum (RUB) have been examining extinct marine creatures. Quantitative analyses provide new evidence that ammonites ...
