In a new study published in the journal PLoS ONE, paleontologists analyzed the fossilized remains of the alvarezsaurid dinosaur Bonapartenykus from the Allen Formation of Patagonia. Their results shed ...

The newly-discovered hadrosaurid footprints date back to approximately 70 million years ago (Cretaceous period). One of them is around 92 cm (3 feet) across, making it one of the largest hadrosaurid ...

A team of planetary researchers led by Caltech has determined the chemical mechanisms by which the ancient Mars was able to sustain enough warmth in its early days to host water, and possibly life.

The newly-discovered volcanic hotspot is larger than Earth’s Lake Superior, and belches out eruptions six times the total energy of all the world’s power plants. “NASA’s Juno spacecraft had two really ...

Written in Greek, this papyrus is a memorandum for a judicial hearing before a Roman official in the province of Judea or Arabia in the reign of the Roman emperor Hadrian, after his visit to the ...

New data from NASA’s Chandra X-ray Observatory and ESO’s Very Large Telescope provide evidence that outbursts from supermassive black holes can help cool down gas to feed themselves. In a new study, ...

Labrys portucalensis F11, a strain of aerobic bacterium from the Xanthobacteraceae family, can break down and transform at least three types of per- and polyfluoroalkyl substances (PFAS), and some of ...

Physicists with the CMS Collaboration at CERN’s Large Hadron Collider have tested whether top quarks adhere to Albert Einstein’s special theory of relativity. Along with quantum mechanics, Albert ...

Understanding food chains in ancient ecosystems is one of the goals of paleoecology. Direct evidence for these interactions is rare and includes fossils with stomach contents and bite/tooth marks.

A nearly complete but strongly flattened skull of the ancient bird species Diatryma geiselensis has been discovered, after being misidentified and kept in a museum collection in Germany for over six ...

Paleontologists have discovered a set of ancient bear footprints in Honseca Cave, northern Spain. Although distinguishing cave bear from brown bear tracks is complex, cave bears are considered the ...

In a study published in the journal Nature Geoscience, planetary researchers used high-resolution images and compositional data captured by orbiters to understand the geology of thousands of kilometer ...
