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 ...

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 ...

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 ...

A small team of researchers from Germany, Mexico and the U.K. has found evidence suggesting that the reason a species of ammonite grew into giants was because of the increasing size of the mosasaurs ...

Jack Wonfor (pictured) is among the fossil hunters on the Isle of Wight who found a 211-pound fossilized seashell. It’s a 115-million-year-old ammonite, best described as a “squid-like cephalopod ...

Robotic ammonites, evaluated in a university pool, allow researchers to explore questions about how shell shapes affected swimming ability. They found trade-offs between stability in the water and ...

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 ...
