The earliest dinosaurs were carnivorous, omnivorous and herbivorous, according to new research.

The long-necked diplodocid sauropod dinosaurs were believed to be able to whip their tails at supersonic speeds. A new study explains why that isn't possible.

The dinosaur, which has been named Natovenator polydontus, was discovered in the Omnogovi Province of Mongolia

A “mega-earthquake” is estimated to have included 50,000 times the energy than was released during the Sumatra earthquake in 2004 that recorded 9.1 on the Richter Scale.

The tsunami that killed the dinosaurs was strong enough to disturb and erode sediments in ocean basins halfway around the globe.

For years, scientists have been stumped as to what caused the golf ball-sized holes in the skull of one of the world's best-known dinosaur fossils.

If you are one to fear large sharks, and if the movies Jaws or The Meg terrified you, then the megalodon, the massive prehistoric selachians, are likely the stuff of nightmares.

Archaeologists have uncovered a fossilized skeleton of a small ancient reptile that is long gone, but one direct relative still thrives in New Zealand.

The research that went into these discoveries was published on Wednesday in Nature. Mbiresaurus was a sauropodomorph, a long-necked dinosaur, and is estimated to have been about six feet tall.

The tracks most likely belonged to an acrocanthosaurus, who roamed North America around 113 million years ago.
