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 ...
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 ...
Despite their incredible success, ammonites died out at the end of the Cretaceous in the same mass extinction that killed the ...
The ammonoids, an extinct subclass of cephalopods, offer a remarkable window into the evolutionary innovations of marine life. Their coiled, chambered shells and intricate suture patterns record a ...
Some fossils of long-extinct sea creatures display brilliant rainbow colors. Known as ammolite, these gems come from the fossilized shells of ammonites, squid-like marine animals that vanished with ...
Add Yahoo as a preferred source to see more of our stories on Google. One of the distinguishing characteristics of Ohio’s indigenous American Indian Hopewell culture, which dates from around AD 1 to ...
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 ...
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 ...
