Cambrian paleontology and geology represent a critical juncture in Earth’s history, marked by the rapid diversification of animal life and profound shifts in marine geochemistry. The early Cambrian ...

How can we measure time more than 500 million years into the past? A study recently published in Nature Communications by researchers at the University of Lausanne presents a new geological "rock ...

There's a billion-year gap in Earth's geological history. A new study seeks to explain the mystery.

A sudden explosion of new life-forms hundreds of millions of years ago may have been triggered by a major tectonic shift, new research shows. About 530 million years ago, the Cambrian explosion ...

A new analysis of geologic history may help solve the riddle of the "Cambrian explosion," the rapid diversification of animal life in the fossil record 530 million years ago that has puzzled ...

Geoscientists employed current-day stratigraphic, depositional and paleontological models, along with modern technological muscle to provide updated insights of the Cambrian period of the Grand Canyon ...

DURING the Cambrian period, which began 541m years ago, animal life took a remarkable leap forward. The first creatures believed by most (though not all) palaeontologists to be multicellular animals ...

AMONG the mysteries of evolution, one of the most profound is what exactly happened at the beginning of the Cambrian period. Before that period, which started 541m years ago and ran on for 56m years, ...
