The complex social behaviour in early dinosaurs observed in a new study lines up with other fossil evidence that dinosaurs were more bird-like than crocodilian-like.

An asteroid strike 66 million years ago wiped out the non-avian dinosaurs and devastated the Earth’s forests, but tree-dwelling ancestors of primates may have

New research sheds light on two dinosaurs that once roamed what is now the eastern United States, including a cousin of the Tyrannosaurus rex.

"The new pterosaur, which we named Thapunngaka shawi... was essentially just a skull with a long neck, bolted on a pair of long wings."

The unique shape of their brains may help explain why birds are the only dinosaurs left on Earth.

The global climate during the late Cretaceous Period, an era when dinosaurs ruled the planet, was warmer and more varied than previously believed.

When dinosaurs were having their heyday in the late Cretaceous 78 million years temperatures were about two degrees warmer—and more volatile than thought.

When they bit down, young T. rexes exerted up to 5,641 newtons of force. That's somewhere between the jaw forces exerted by a hyena and a crocodile.

The inner ear may clue paleontologist in on two particular phenomena: how dinosaurs interacted with each other and how they began to fly.

By looking at the eye bones and ear canals of extinct dinosaurs, researchers show that a small ancient predator likely hunted at night and had senses as good as a modern barn owl.
