Ammonites survived the asteroid that killed the dinosaurs, so what killed them not long after?
Evidence for ammonite survival into the Paleogene era is solid, a new study confirms, indicating that these ancient mollusks were well positioned to inherit oceans now cleared of competitors. Yet for ...
Los Angeles, CA (June 27, 2024) —A new study published in the journal Nature Communications led by paleontologists at the University of Bristol along with a team of international researchers, ...
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 ...
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 ...
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 ...
The ammonoids, an extinct subclass of cephalopods, offer a remarkable window into the evolutionary innovations of marine life. Their coiled, chambered shells and intricate suture patterns record a ...
