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 ...

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 ...

When I was searching for ammonite fossils last year, I tended to concentrate on searching out the distinctive coiled shapes that were the shells of these once-abundant marine invertebrates. Other ...

Although ammonites have been extinct for 65 million years, newly published data based on 35 years of field work and analysis is providing invaluable insights into their paleobiology. Ammonites, ...

New research presented at the European Geosciences Union General Assembly challenges the idea that geographic range determined why nautiloids survived the end-Cretaceous extinction while ammonites ...

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 ...

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 ...

Several years ago, back when I was working as the lab and collections manager for the St. George Dinosaur Discovery Site in St. George, Utah, we constructed a temporary exhibit with hundreds of ...

For the first time, 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 siphons ...
