Lather, rinse, repeat. And it all started – at least, for complex life as we think of it today – with the Cambrian explosion. It was during this period, around 530 million years ago, that basically ...

A new study of ancient fossil trails pushes the origins of complex life deeper into Earth’s history, before the Cambrian Period began.

New fossils of a Cambrian animal called Stromatoveris showed that it’s related to an Ediacaran group called the petalonamids, named for their petal-like fronds.

This period, taking place some 541-530 million years ago, marks the origins of most modern animal life. But, a second look at these fossils might indicate that’s not such a great fit after all.

A new analysis of the extinct marine animal Anomalocaris canadensis suggests the Cambrian hunter was more of a weakling than once assumed.

The soft-bodied animals are also a connection to the ancient past. Now, researchers have uncovered a 508-million-year-old fossil of a bygone jellyfish, possibly representing the oldest swimming ...
