Specifically, he and his colleagues looked at uranium in limestone that had formed in shallow Ediacaran and Cambrian seas. Uranium has two isotopes, 235 U and 238 U, ...

The Ediacaran period ended around 540 million years ago, just before the Cambrian period, which saw a massive explosion in marine animal life.

Fossils offer a glimpse into Earth's ancient life, revealing the origins and evolution of complex organisms. Discoveries like ...

As Ediacaran organisms became more specialized, some species couldn’t keep up with their neighbors, the team reported on May 17 in the journal PLoS Biology.

Sorting out the way these 570- to 540-million-year-old, enigmatic creatures ate supports the argument that they behaved like more modern-looking animals and evolved into shapes that helped them feed.

"Ediacaran biota is when life got very big, very fast," Dr Brocks said. "Then 540 million years ago, they go extinct." After that, he said, we start to see fossils of animals with claws, armour ...

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 ...
