Announcing the completion of time-consuming “cleaning” work, a research team in Hokkaido has unveiled what it claims is the largest dinosaur skeleton ever found in Japan. Through the work to remove rocks and sediments in which the fossils were embedded, a total of 157 pieces were identified as bones of a large herbivorous dinosaur from the Hadrosaurid family, according to the team comprising curators of the Hobetsu Museum in Mukawa, Hokkaido, and Yoshitsugu Kobayashi, an associate professor at the Hokkaido University Museum.

It's known as the "Great Dying," an extinction event even more powerful than the one that killed the dinosaurs 65 million years ago. It's called the Permian-Triassic extinction event, and it took place 250 million years ago, before dinosaurs ruled the Earth. Scientists previously believed the Permian-Triassic extinction event happened because of a volcanic eruption. And not just any volcanic eruption... the volcanic eruption. Called the "Siberian Flood Basalts," this million-year-long volcanic eruption potentially caused the extinction of up to 96 percent of marine life, along with 70 percent of terrestrial vertebrate species.

It led to an explosion of interest in dinosaurs, and by extension, people interested in researching them

Gerta keller was waiting for me at the Mumbai airport so we could catch a flight to Hyderabad and go hunt rocks. “You won’t die,” she told me cheerfully as soon as I’d said hello. “I’ll bring you back.” Death was not something I’d considered as a possible consequence of traveling with Keller, a 73-year-old paleontology and geology professor at Princeton University. She looked harmless enough: thin, with a blunt bob, wearing gray nylon pants and hiking boots, and carrying an insulated ShopRite supermarket bag by way of a purse.

With a bill like a duck but teeth like a croc’s, a swanlike neck and killer claws, a new dinosaur species uncovered by scientists looks like something Dr. Seuss could have dreamed up. By Seth Borenstein.

Trapped in 100-million-year-old amber, the fossils are the first ever evidence linking ticks to a dinosaur host. In a discovery that seems straight out of Jurassic Park, researchers have identified a 99-million-year-old fossilized tick on a dinosaur feather.

Cranial bones of three primitive horned dinosaurs have been found in a Lower Cretaceous stratum in Sasayama, Hyogo Prefecture, the Museum of Nature and Human Activities said Saturday. Noting that the ages of the dinosaurs are different, the prefectural museum hopes that the bones can clarify the developmental process of the species.

New research suggests we've misunderstood the legs of these prehistoric flyers.

On 4 June, geological hammers will give way to an auctioneer’s gavel as the fossilized skeleton of a gigantic predatory dinosaur goes up for sale in the Eiffel Tower in Paris, to the dismay of one of the world’s largest international paleontological societies.

Two new species of predatory creatures with giant sabre teeth have been unearthed in Russia. The prehistoric animals belong to a group known as therapsids or “protomammals” that ruled the planet long before the first dinosaurs over 250 million years ago. These creatures would ultimately give rise to modern mammals, but they were largely wiped out by a massive extinction event at the end of the Permian era that made way for the age of the dinosaurs.

Giant dinosaurs lived on Earth much earlier than previously thought, according to a team of excavators in Argentina who discovered the remains of a 200-million-year old species. The species, baptized Ingenia prima, was about three times the size of the largest Triassic dinosaurs from its era. It was discovered in the Balde de Leyes dig site in San Juan province, 1,100 kilometers (680 miles) west of the Argentine capital Buenos Aires.

The studio rolls out the 3D version of Steven Spielberg's 1993 sci-fi adventure on Friday.

Australian mining mogul Clive Palmer wants to establish an island filled with giant, robotic dinosaurs — and that’s not an April Fools’ joke, the AFP reports. Luckily, though, Palmer appears to have moved on from his original dream of cloning a dinosaur and instead has decided to fill his island with giant robotic ones. Perhaps someone finally showed the billionaire Jurassic Park.

No bones about it - students at a Bondi school were thrilled to have a prehistoric visitor.

On June 11, 1993, Steven Spielberg's Jurassic Park hit theaters, wowing audiences with its incredibly lifelike depictions of dinosaurs. It grossed $900 million worldwide. Today, the film is being rereleased in 3D, so we're celebrating its 20th anniversary a little early. Here are 20 things you might not have known about Jurassic Park.

Just how quick was the great tyrant lizard, exactly? Experts in biomechanics think she was pretty damn quick – but still probably not as fast as you think.

Reconstructing dinosaur behaviour – such as the hunting strategy of raptors – is fraught with difficulty.

This specimen is from the Judith River Formation along the Milk River in southern Alberta. It is Campanian (Late Cretaceous) in age, which corresponds to about 80 million years old. It is an example of ideal preservation, and shows all the microstructural features typical of most fossil vertebrate bone. Little or no alteration of the hydroxyapatite appears to have occurred, and a significant amount of the pore space is not infilled with minerals and retains its "spongey" texture.

A new species of dinosaur found in NE China has added further  evidence that feathers developed originally or uses other than flight.

Queensland paleontologists have discovered that the world's only recorded dinosaur stampede is largely made up of the tracks of swimming rather than running animals.
