The late Devonian extinction is one of the five major extinction events to have occurred on Earth. It's not unusual for scientists to argue over what causes a mass extinction event -- of the five, the ...

The cause of the Devonian period extinction 359 million years ago, ranked as one of the five great extinctions of life on Earth, remains a mystery. Now, a new study reveals the explosion of a nearby ...

Most scientists think the dinosaurs — along with countless other creatures — were wiped out some 66 million years ago when a space rock slammed into Earth. But a cosmic impact isn’t the only disaster ...

The Late Devonian mass extinction (roughly 372 million years ago) was one of five mass extinctions in Earth’s history, with roughly 75% of all species disappearing over its course. It happened in two ...

Over the roughly 4.5 billion years of Earth's existence, there have been several periods were biodiversity has been nearly wiped out - extinction events. There have been several proposals to explain ...

Mass extinctions are very important to how life evolved on Earth. For example, when an asteroid hit the Earth 66 million years ago, the resulting dinosaur extinction led mammals to take their place.
