Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified ...
Tribrachidium heraldicum, one of the most enigmatic critters from the Ediacaran fauna. A new study has for the first time precisely dated some of the oldest fossils in the world, helping to track a ...
In 1947, geologist Reginald C. Sprigg announced the discovery of large fossils from the Ediacara Hills in the Australian Outback. Dating of the rock formations revealed that the Ediacaran fauna was ...
University of Rochester researchers studied Earth’s magnetic field during the transformative Ediacaran Period, which spanned from about 635 to 541 million years ago. The research raises questions ...
A global drop in oxygen levels about 550 million years ago led to Earth's first known mass extinction, new evidence suggests. When you purchase through links on our site, we may earn an affiliate ...
