When plants started growing on land, they changed the world. Ancient fossil spores hint at how and when they did it.

Scientist Elizabeth Turner found fossilized evidence of 890-million-year-old sponges. These are possibly the earliest known evidence of animal life on Earth.

Scientists in Australia have classified a new species of dinosaur, discovered in 2007, as the largest ever found on the continent. The Australotitan cooperensis or "the southern titan", is among the 15 largest dinosaurs found worldwide. Experts said the titanosaur would have been up to 6.5m (21ft) tall and 30m long, or "as long as a basketball court".

The bones of their young suggest they were permanent residents, not migrants | Science & technology

Paleontologists classified a new species of sauropod that now ranks as Australia's largest dinosaur. The species was known as Australotitan cooperensis.

Donald Johanson’s book Lucy: The Beginnings of Humankind was what first made me fall in love with paleoanthropology. While I have learned about dozens more fossils over the last two years, I still have a special place in my heart for Lucy. So you can imagine how excited I was to defend her from the lies of the young-earth creationists at Answers in Genesis! I once might not have known how to debunk their claims, but I now have the knowledge, the books, and a little bit of money needed to find so many errors in their articles.

Tilly Edinger was the first person to apply a deep-time perspective into different species' brain evolution. She did this by focusing on the hollow space within a dead animal's skull.

A teeny tiny fossil found in the Scottish Highlands could be a missing link in the evolutionary history of animals.

A team of palaeontologists in Mexico have identified a new species of dinosaur after finding its 72 million-year-old fossilized remains almost a decade ago, Mexico's National Institute of Anthropology and History (INAH) said on Thursday.

Under the cover of darkness in desert habitats about 70 million years ago, in what is today Mongolia and northern China, a gangly looking dinosaur employed excellent night vision and superb hearing to thrive as a menacing pint-sized nocturnal predator.

By analyzing what’s known about the dinosaur, paleontologists conclude there were 2.5 billion T. rex over the 2.4-million-year existence of the species

Although an asteroid impact has long been the suspected cause of the mass extinction 66 million years ago, researchers think new evidence finally closes the case.

New scans of a tiny Cretaceous jaw and claw show the tyrant dinosaurs started out the size of a small dog. THE FIRST KNOWN fossils of baby tyrannosaurs reveal that some of the largest predators ever to stalk the Earth started life about the size of a Chihuahua—with a really long tail.

The skeleton is still far from complete but paleontologists say what they've found suggests the dinosaur may be more than 120 feet long

When a dog-sized Psittacosaurus was living out its days on Earth, it was probably concerned with mating, eating, and not being killed by other dinosaurs. It would never even have crossed its mind that, 120 million or so years later, scientists would

We know a lot about dinosaurs -- what they looked like, what they ate and what killed them off -- but no fossils have definitively preserved two dinosaurs in the act of mating.

Paleontologists uncovered a great deal about the “terrible lizards” this year

One theory is that reckless young bison and mammoths got into more trouble.

A Brazilian dinosaur with stiffened pairs of ribbonlike feathers emerging from the shoulders is unlike any found before.

For the entirety of my career as a journalist covering paleontology, I’ve been wanting to know: What does a dinosaur’s butthole look like? When I wrote My Beloved Brontosaurus, a book about dinosaur biology, the chapter on reproduction required a lot of time imagining the nature of a Jurassic behind; one had yet to be found preserved. Even dinosaur models and sculptures often demur on the point of the dino butt, leaving the terrible lizards with terrible constipation.
