The muscles and organs of an ammonite — an extinct relative of cuttlefish and squid with coiled shells and tentacles — have been reconstructed in 3D for the first time. The achievement has allowed a ...

Opalized ammonite fossils are some of the most unique and spectacular paleontological specimens. They were formed through a geological process known as opalization, wherein organic material from ...

In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% ...

One of the distinguishing characteristics of Ohio’s indigenous American Indian Hopewell culture, which dates from around AD 1 to 400, is the use of unusual raw materials that found their way into Ohio ...

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 ...

A giant fossil ammonite has been recovered from a fallen boulder on a beach. The edge of the creature's shell was spotted in the block by fossil collector Jack Wonfor on the Isle of Wight's southwest ...

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 ...

Ammonites are among the most common marine fossils from the age of the dinosaurs, but no one has found one like this before. It shows one of the swimming marine molluscs without its distinctive spiral ...
