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 ...

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 ...

The narrower shells, for example, produced less drag and were more stable when moving straight through the water. The wider shells, while making for slower, less energy-efficient travel, could change ...

Scientists devised a mathematic model that helps explains how Nipponites, some of the wonkiest ammonites, built their shells. By Sabrina Imbler If you’ve seen one ammonite, you may think you’ve seen ...

In an interesting discovery, paleontologists from Universität Hohenheim's Staatliches Museum für Naturkunde Stuttgart have unearthed a fossilized fish that tells of a tale of a meal gone awry from 180 ...

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 ...

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 ...

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 ...

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 ...
