Using state-of-the-art imaging techniques, palaeontologists at the Ruhr-Universität Bochum (RUB) have been examining extinct marine creatures. Quantitative analyses provide new evidence that ammonites ...

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 ...

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 ...

Ammonites are a tale of two textures. The prehistoric cephalopods were composed of fleshy soft tissue (the living bit of the animals) and hard external shells, which, according to a paper published ...

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 ...

Earth once hosted more than 10,000 species of these ancient marine predators. Find out how they lived, when they vanished, and how much we know about them today. Based on the fossil record, ammonites ...

Like the rest of the West Coast, far Northern California was under water when early dinosaurs roamed North America. That doesn’t mean what would become Shasta County didn’t have its own amazing ...

Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living ...

Some extinct species left copious fossil remnants of their existence. Ammonites—an extinct type of cephalopod—are one such example. From the Devonian through the Paleocene, wherever ancient seas once ...

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 ...

Meet Shasta County's ancient predators, some that dwarfed Tyrannosaurus rex Ancient ancestors to squid swam in the salty water that once covered Redding Prehistoric 10-foot 'sea lizard' once lived in ...
