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 ...
Millions of years ago, South Dakota was covered by a vast inland sea. This ancient seaway supported diverse marine life, ...
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 ...
Spectacular marine fossils tell the story of the long-gone Western Interior Seaway and the planet’s past aquatic life ...
(Phys.org)—A team of workers with members from institutions in the U.K., Germany and Spain has put online a digitized 3-D model of the "death drag" of an ammonite fossil—it is one of the longest ever ...
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 ...
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 ...
