The earliest multicelled animals that survived the Precambrian fall into three main categories. The simplest of these soft-bodied creatures were sponges.

The red was rust — an oxidized form of iron pyrite, which commonly appears on local Precambrian fossil beds. They scrambled down the bluff to inspect it. There, Liu spotted what many other ...

Newly discovered fossil records hint that mold-like unicellular organisms — the common ancestor to all complex life on our planet — arrived over a billion years earlier than previous estimates.

A team of researchers challenged the belief that complex life forms first emerged on Earth 635 million years ago, saying life ...

The Precambrian was the first super eon of Earth’s history. This division of time — about seven-eighths of Earth's history — lasted from the first formation of the planet (about 4.6 billion ...

Furthermore, the Precambrian fossil record shows that early microbiotic organisms adapted to land-based stresses, developing a “lotion” to screen out solar radiation, for example. This counters the ...

"Animals, plants, seaweed, and foraminifera are all eukaryotes. We were interested in studying this foraminifera because it thrives in a very similar environment to Earth during the Precambrian, a ...

Precambrian fossils, once thought to be embryos, reinterpreted as ... That clearly eliminates bacteria as a source of these fossils, and would appear to put metazoans back on the table, ...

Furthermore, the Precambrian fossil record shows that early microbiotic organisms adapted to land-based stresses, developing a “lotion” to screen out solar radiation, for example.

The strange creatures that lived in the Garden of the Ediacaran more than 540 million years ago, before animals came on the scene, may have been much more dynamic than experts have thought.

MILWAUKEE, March 22 (UPI) --Researchers have discovered some of the oldest evidence of multicellular organisms. Scientists hope the newly discovered marine algae fossils, ancient ancestors of ...

In addition, Dendrogramma seems to share features with some extinct Precambrian organisms that date back to 600 million years ago, the researchers report today in the journal PLOS ONE.
