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 ...
Some of the fossils celebrated as sea life’s big breakout beyond mere soups and slimes might actually have dwelled on land, argues a controversial new study. Named the Ediacaran fauna after ...
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 ...
Ancestors of today’s animals can be traced back 540 million years to the relatively sudden appearance of most major animal groups during a time called the Cambrian explosion. Before then, nebulous ...
Animals originated in a world with marine oxygen levels only a fraction of those found in today's oceans. Observations of microbial habitats in present-day lagoons suggest that early animals could ...
