Scientists examining an ancient Aboriginal site are split over whether charred rocks and weather-worn shells are 120,000-year-old evidence of Indigenous life.

Fossilised sperm discovered inside a mussel-like crustacean that was trapped in amber 100 million years ago may be the oldest ever found, scientists say. The female ostracod was unearthed by an international team of palaeontologists. They believe it mated shortly before becoming trapped in the resin. Their findings, published in Proceedings of the Royal Society B, provide "an extremely rare opportunity" to learn more about the evolution of the reproductive process, they added.

Huge volcanic eruptions 233 million years ago pumped carbon dioxide, methane, and water vapour into the atmosphere. This series of violent explosions, on what we now know as the west coast of Canada, led to massive global warming.

Several complete skeletons of the unusual feathered two-fingered dinosaurs were unearthed in the Gobi Desert.

Buyer unknown, but paleontologists worry researchers will lose access

He was hiking with his father in Alberta, Canada, when he stumbled upon the Hadrosaur remains.

A newly discovered "King of Gore" tyrannosaur pushes back the origins of T. rex's terrifying family tree to at least 80 million years ago, report paleontologists.

The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to new research, iron in the dinosaur's body preserved the tissue before it could decay.

A new horse species, which roamed the Earth approximately 4.4 million years ago, has been discovered from fossils found in Ethiopia, scientists are reporting. Scott Simpson, who is a professor of anatomy at Case Western School of Medicine, and is also one of the chief scientists over this research study, stated that the horse fossils that were discovered were only a few pieces of an extremely complex puzzle which included many parts.

Neanderthals died out long ago, but their genes live on in us. Scientists studying human chromosomes say they've discovered a surprising amount of Neanderthal DNA in our genes. And these aren't just random fragments; they help shape what we look like today, including our hair and skin.

Scientists have discovered the fossil remains of an ancient marine reptile in the act of being born.

The teenage boys couldn't resist posing for selfies with the stars of the show. It didn't matter that these stars were the famous dinosaur fossils at the American Museum of Natural History in New York City. If you think kids outgrow dinosaurs by kindergarten, think again. "The dinosaurs were amazing. It is astounding that these creatures once roamed the Earth," said Khaliq Sanda, a high school senior.

Sharks turn out to be more modern and sleek than anyone had ever imagined, given a new study that negates a prior theory that today’s sharks are “living fossils,” changing little over time.

A new type of Tyrannosaur with a very long nose has been nicknamed "Pinocchio rex". The ferocious carnivore, nine metres long with a distinctive horny snout, was a cousin of Tyrannosaurus rex. Its skeleton was dug up in a Chinese construction site and identified by scientists at Edinburgh University, UK.

The world's oldest and best preserved sperm has been discovered in 17 million-year-old fossils unearthed in far north Queensland. The sperm of an ancient species of freshwater shrimp, which were found inside a rock taken from the Riversleigh World Heritage area, were not only hardy, but huge compared to the animal's body size. The not-so-little swimmers were as long as the crustacean itself, which was only a couple of millimetres in length.

The case was cold, but critical clues pointed to a killer's identity in ancient Madagascar

In the dinosaur kingdom, the raptor reigns as a pop-culture bogeyman. While not as big as the T. Rex, the feathered creature had a mean set of teeth and claws. But there was at least one refuge from its tyranny: the air.

Dinosaurs were lumbering, stupid, scientifically boring beasts—until John Ostrom rewrote the book on them.

Dinosaurs were wiped out by an asteroid impact when they were at their most vulnerable, according to a new study. Dr Steve Brusatte, of Edinburgh University, said sea level rises and volcanic activity had made many species more susceptible to extinction. They might have survived if the asteroid had hit the Earth a few million years later or earlier, he said, calling it "colossal bad luck".
