A clutch of marine fossil specimens unearthed in northern Portugal that lived between 470 and 459 million years ago is filling a gap in understanding evolution during the Middle Ordovician period.

Newly discovered fossilized tracks suggest multicellular life could be 1.5 billion years older than previously thought, according to a new study by an international team of researchers including scientists at the University of Alberta.

All over the world, spectacular fossils have frequently been found preserved inside solid, roughly spherical rocks called "concretions."

Take a good look at these photos: They show you 1.6 billion years old fossilized oxygen bubbles, created by tiny microbes in what was once a shallow sea somewhere on young Earth.

Keith's Note: NASA recently posted an image taken by the Mars Hand Lens Imager (MAHLI) aboard NASA's Mars rover Curiosity. A reader from Australia contacted me to point out some curious structures within the rock featured in that image.

Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth.

One of the primary open questions of astrobiology is whether there is extant or extinct life elsewhere the Solar System.

Large, robust, lens-shaped microfossils from the approximately 3.4 billion-year-old Kromberg Formation of the Kaapvaal Craton in eastern South Africa are not only among the oldest elaborate microorganisms known.

The origin of animals was one of the most important events in the history of Earth. Beautifully preserved fossil embryos suggest that our oldest ancestors might have existed a little more than half a billion years ago.

Fossils discovered by UNSW scientists in ancient hot spring deposits in the Pilbara have pushed back by 580 million years the earliest known evidence for microbial life on land.
