The brilliant iridescent hues found in ammolite come from tiny air gaps in the fossils’ layers, a new study finds.

Ammolite comes from the fossilized shells of extinct squidlike critters called ammonites. Scientists knew the secret to the fossils’ flamboyant appearance lay somewhere in their layers of nacre, or ...

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 ...

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 ...

An enormous fossil weighing almost 210 pounds and measuring around two feet in diameter has been found on the Isle of Wight. The ammonite was spotted and pried loose from surrounding rock by ...

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 ...

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 ...

A shelled fossil discovered in an amateur’s collection may harbor the first direct evidence of prehistoric sharks eating ammonites some 150 million years ago. The palm-sized ammonite, an extinct ...

“Ammonite” will be compared to last year’s critical favorite “Portrait of a Lady on Fire,” and not unfairly. The two films take place on either side of the year 1800 on either side of the English ...

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 ...
