A new study by the University of Minnesota challenges previous classifications paleontologists use to determine how the fossil record is formed. They investigated how dinosaur and mammal bones are ...

Iguanodontians are a diverse group of herbivorous dinosaurs that lived from the Late Jurassic to the Late Cretaceous and had ...

A new study published in Palaeontology has confirmed that X-ray computed tomography (XCT scanning) can be used to monitor decomposing organisms without altering the natural decay process—a vital step ...

Before this discovery, the earliest widely accepted cephalopod was Plectronoceras cambria, which lived during the late ...

Scientists confirm CT scanning doesn't interfere with natural decomposition processes, opening new windows into understanding how fossils form. Scientists have found that X-Ray scanning reveals ...

Join paleontologist Harrison Duran at the Hell Creek Formation as he uncovers a real T-Rex tooth. Watch as he carefully brushes away sediment, stabilizes the fossil on site, and reveals a stunning, ...

One of the most extraordinary fossil beds of Cretaceous creatures in the world formed about 125 million years ago, in what’s now northeastern China. Researchers have thought that the diverse members ...

Scientists believe they've deduced why prehistoric Ediacara Biota fossils have remained preserved for millions of years. The fossils of these soft-bodied creatures from before the Cambrian Explosion ...

Scientists know that dinosaur fossils are millions of years old by dating radioactive elements in rocks that the fossils were found near or in. Soft tissue can exist in fossils for longer than 4 ...
