Imagine stepping back in time to Earth 2 billion years ago,long before forests, dinosaurs, or even fish. Step into Earth’s ...

Imagine stepping back 200 million years into a world vastly different from the Earth we know today. During the age of dinosaurs, one colossal landmass, Pangaea, dominated the surface, surrounded by ...

A study of fossils from the Permian-Triassic extinction event 252 million years ago shows that forests in many parts of the ...

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

Astronomers estimate that an asteroid this large comes this close to Earth only about once every 7,500 years. It also appears ...

The older data sets only used a few measurements between 90 and 75 million years ago. They also lacked modern tools like superconducting magnetometers and precise thermal demagnetization techniques.

From 3 billion years ago to roughly 600 million years ago—right at the dawn of complex life on the planet—the Earth’s oceans would’ve been significantly more green than they are today.

Scientists studying the geology of the Ordovician Period about 466 million years ago report evidence that Earth's ring system created a telltale pattern of impact craters, and it may also explain ...

Anyone living on Earth between 720 million and 635 million years ago probably would've needed a jacket. Geologists have long suspected that Earth's temperature dropped dramatically during this ...

Travel back in time even further to around 250 million years ago, and the Great Dying – more formally known as the Permian-Triassic extinction event – wiped out members of all classes of life.

What if our Earth, about 800 million years ago, was home to an abundance of diverse lineages of life — far more than the conventional evolution theories suggested? This is the conclusion of a group of ...
