Life was already getting harder for dinosaurs before an asteroid wiped them out.
If the asteroid caused the very sudden end of the dinosaurs, a new study shows that their decline had begun 10 million years earlier.

This is a crucial dinosaur for palaeontologists; the variety of fossils available means researchers can study the species’ growth through its whole life span.

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.

The azhdarchid pterosaur, the largest flying animal ever known.
Gigantic flying reptiles had impressive wingspans of up to 12 metres – and a special trick in their necks.
The environmental, cultural and scientific sensitivity of some sites, and rarity of some fossils, means amateur fossil collecting comes with huge risks.
The ferocious dinosaur.
Our new study has found younger tyrannosaurs would have hunted small prey.

Because of its skeleton’s heavy architecture, scientists have always assumed that Anteosaurus was a rather sluggish, slow-moving animal, only capable of scavenging or ambushing its prey, at best.
A large impact.
A new study found iridium, an element found in asteroids, in the rocks of the Chicxulub impact crater.

A reconstruction of a dinosaur’s back passage reveals it may have been used for visual communication.
Crocodiles have not evolved much in the past 200 million years.
New research shows crocodiles have landed upon an equilibrium state of evolution.
Anomalocaris, with its large stalked eyes, is considered a top predator that swam in the oceans more than 500 million years ago.
Our study on weird ancient marine animals called radiodonts supports the idea that vision played a crucial role during the Cambrian Explosion, a rapid burst of evolution about 500 million years ago.
66 million years ago, birds survived the calamity that wiped out all prehistoric dinosaurs. But could birds once again evolve into their long lost ancestors?

The end-Triassic mass extinction was a cataclysm for the world’s prehistoric species, killed off by volcanoes that altered Earth’s seas and skies. But new research shows it didn’t happen when we thought.
Did feathers evolve in the common ancestor of pterosaurs and dinosaurs? Not everyone is convinced
