The asteroid that struck Earth 66 million years ago, wiping out three-quarters of the planet's plant and animal life (most famously the dinosaurs), also triggered a worldwide tsunami with mile-high wa

A P.E.I. school teacher has made the discovery of a lifetime after stumbling upon a fossil that could be 300 million years old. Lisa Cormier was taking a stroll in Cape Egmont Monday afternoon when she spotted something unusual partially buried on the shore.

A 25-metre fossilised dinosaur skeleton was the last thing a Portugal man expected to uncover in his own backyard in 2017, but now researchers believe he may have stumbled upon the largest of its kind in Europe.

Pterosaurs not only had feathers, but also were flamboyantly colorful, scientists say. That could mean that feathers — and vibrant displays of mate-seeking plumage — may have originated as far back as the common ancestor of dinosaurs and pterosaurs, during the early Triassic Period around 250 million years ago.

Few researchers have given credence to claims that samples of dinosaur DNA have survived to the present day, but no one knew just how long it would take for genetic material to fall apart. Now, a study of fossils found in New Zealand is laying the matter to rest — and putting an end to hopes of cloning a Tyrannosaurus rex.

Self-taught fossil specialist Terry Manning uncovered his first dinosaur embryo from an ancient egg in 1993. More than 30 embryos and nearly three decades later, hardly anyone has laid eyes or hands on his rare specimens.

Spikes in this ankylosaur is peculiar since it is fused to the rib bones and not growing out from skin

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".

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

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.

How can All Things Considered consider all things without considering dinosaurs? That's the question posed by 8-year-old Leo Shidla of Minneapolis.

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

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

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.
