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 ...

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 ...

Ammonites are a group of extinct cephalopod mollusks with ribbed spiral shells. They are exceptionally diverse and well known to fossil lovers. Researchers have developed the first biomechanical model ...

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 sea creature that lived 99 million years ago has been found preserved in amber in an ultra-rare finding. The fossil, found in northern Myanmar, is the first ever known example of an ammonite to be ...

Ammonites – the ancient relatives of squid and octopuses – left behind some of the most common and beautiful fossils. But look closely at their elegant, spiral shells and you might be able to spot a ...

Beautifully preserved fossil ammonite collected from 165-million-year-old Jurassic site in Gloucestershire, UK; 3D reconstruction of combined neutron and X-ray images of fossil shows internal muscles ...

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 ...

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 ...
