The origin of reptiles on Earth has been shown to be up to 40 million years earlier than previously thought -- thanks to evidence discovered at an Australian fossil site that represents a critical time period. Scientists have identified fossilized tracks of an amniote with clawed feet -- most probably a reptile -- from the Carboniferous period, about 350 million years ago.

The footprints of a reptile-like creature appear to have been laid down around 356 million years ago, pushing back the earliest known instance of animals emerging from the water to live on land

Scientists have now discovered the oldest ancestor for all the Australian tree frogs, with distant links to the tree frogs of South America.

Archaeopteryx is the fossil that clearly demonstrated Darwin's views. It's the oldest known fossil bird, and it helps show that all birds -- including the ones alive today -- emerged from dinosaurs. And while the first Archaeopteryx fossil was found more than 160 years ago, scientists are continuing to learn new things about this ancient animal. A set of feathers never before seen in this species help explain why it could fly when many of its non-bird dinosaur cousins could not.

Scientists confirm CT scanning doesn't interfere with natural decomposition processes, opening new windows into understanding how fossils form.

Palaeontologists have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. Mosura fentoni was about the size of your index finger and had three eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an extinct group known as the radiodonts.

Originally from South America, the charismatic tegu made its way to the United States via the pet trade of the 1990s. But a recent discovery shows these reptiles are no strangers to the region -- tegus were here millions of years before their modern relatives arrived in pet carriers.

Scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and reveals a critical piece of the ancient history of Asia's rainforests, highlighting the urgent need for conservation in the region, according to researchers.

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose -- and how it protected our ancestors from ancient diseases.

The Arctic landscape during the Cretaceous Period may have been dominated by the dinosaurs, but the rivers and streams held something more familiar. Alaska's fresh waters 73 million years ago were teeming with the ancient relatives of today's salmon, pike and other northern fish. A new article has named three new species of fish from that time period, including a salmonid, dubbed Sivulliusalmo alaskensis.
