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.

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

Buyer unknown, but paleontologists worry researchers will lose access

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

While many fossils have been flattened by time and the elements, a titanosaur found in an egg was preserved in three dimensions.

Four bones found at Shanklin belonged to a new species of theropod dinosaur, a study finds.

A 66m-year-old murder mystery has finally been solved, researchers say, revealing an enormous asteroid struck the killer blow for the dinosaurs. The Cretaceous/Paleogene extinction event resulted in about 75% of plants and animals – including non-avian dinosaurs – being wiped out. But the driving cause of the catastrophe has been a topic of hot debate.
