Rather than a juvenile of a known species, several fossilized bones represent a new species – and shed light on the question of whether dinosaurs were already in decline before disaster struck.
Studying impact craters can broaden our understanding of the Earth’s evolution and life, as well as its possible future.
A recent BBC documentary examined fossils thought to have been made when an asteroid wiped out the dinosaurs.
An analysis of the skull suggests the ankylosaur may have had a poorer sense of smell than its counterparts in the northern hemisphere.
A recent study provides additional evidence that the dinosaurs died in June.
Crocodiles can survive without food for a long time – even up to more than a year – because of how well they can save their energy.
If the asteroid caused the very sudden end of the dinosaurs, a new study shows that their decline had begun 10 million years earlier.
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?
When the dinosaurs went extinct, some species took over the world. Adaptability, not survivability, explains why.
The risks to nature from man-made global warming – and the imperative to act – are clear.
A mass extinction 66 million years ago killed the non-bird dinosaurs, but plants survived.
The asteroid that wiped out the dinosaurs sparked global firestorms. On land, only creatures that could evade fire survived
Sometimes the only way to tell the difference between a baby dinosaur and a grown-up one is to find fossils of them both together.
Every cloud has a silver lining – even the debris cloud from an asteroid impact
Dinosaurs ruled the Earth for about 180 million years. But around 66 million years ago, a huge rock from outer space (called an asteroid) smashed into the Earth. Then things got worse for dinosaurs.
If you’ve never heard of a form of wave called a ‘seiche’ – which can occur in swimming pools during earthquakes – this is your chance to catch up.
More evidence that the asteroid hit on Earth that marked the end of the dinosaurs could have triggered a deadly increase in volcanic activity.
We know of about 900 valid dinosaur species that existed. ‘Valid’ means scientists know the dinosaur from enough of the skeleton bones to feel pretty sure that it differs from other known dinosaurs.
Jurassic Park’s dinosaur DNA premise is not so simple in real life
