A shelled fossil discovered in an amateur’s collection may harbor the first direct evidence of prehistoric sharks eating ammonites some 150 million years ago. The palm-sized ammonite, an extinct ...

Ammonites are a tale of two textures. The prehistoric cephalopods were composed of fleshy soft tissue (the living bit of the animals) and hard external shells, which, according to a paper published ...

The muscles and organs of an ammonite — an extinct relative of cuttlefish and squid with coiled shells and tentacles — have been reconstructed in 3D for the first time. The achievement has allowed a ...

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 ...

There were also air-filled voids and counterweights, in order to replicate the weight distribution of the existing nautilus – it's the only present-day cephalopod with a shell. What's more, the robots ...

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 ...

If you’ve ever been in a shop that sells fossils — the natural history museum gift shop, the nature store in the mall, and so on — you’ve probably seen an ammonite. Its chambered coils make a distinct ...

Beautifully preserved fossil ammonite collected from 165-million-year-old Jurassic site in Gloucestershire, UK; 3D reconstruction of combined neutron and X-ray images of fossil shows internal muscles ...

There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science ...

BEND, Ore. — As her mother cheered from the sideline of a JV soccer game last fall in Bend, 7-year-old Naomi Vaughan went off to play in the nearby sagebrush surrounding the soccer fields. Naomi ...

In a university swimming pool, scientists and their underwater cameras watch carefully as a coiled shell is released from a pair of metal tongs. The shell begins to move under its own power, giving ...
