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
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
The mass extinction of the dinosaurs was down to the location of the asteroid's impact and the kind of rocks it landed on.
Their days were numbered for quite some time ...
New research suggests the Chicxulub asteroid impact threw up billions of tons of oil soot that blocked out the sun for a decade.
Think you know all about the dinosaurs? You might be surprised.
New research reveals that mammals didn't wait for the dinosaurs to die out before starting their rapid spread.
Was there a 'dinosaur Pompeii' in China? New research questions the claim.
A cosmological event could have unleased the huge comet or asteroid that led to the demise of the dinosaurs.
Jurassic World is opening in cinemas this Thursday and again raises the idea of resurrecting extinct creatures. But there's plenty of other contenders before we even think of recreating dinosaurs.
Fossils of the oldest bird ever pushes back the evolutionary record for birds by nearly six million years.
