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 ...

A geology professor and his student at Rogers State University (RSU) made a remarkable discovery just before spring break. Dr. Chris Shelton and student Kolby Dooling unearthed a rare, well-preserved ...

For over 300 million years, the ammonites ruled the prehistoric seas. Finding an ammonite fossil isn’t particularly rare (they can be unearthed all over the world) but they’re still thrilling to ...

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 were not in decline before their extinction, scientists have found. Ammonites were not in decline before their extinction, scientists have found. The marine molluscs with coiled shells and ...

A new study published in Scientific Reports suggests ammonites did not vanish immediately after the asteroid impact 66 million years ago. Fossils from Denmark indicate some survived for up to 200,000 ...

They found that the now-extinct molluscs sported hyponomes: tube-like syphons through which water is expelled to jet propel animals forward in water, as found in modern squid and octopuses. They also ...
