Data from the latest investigations conducted by researchers in the United States demonstrate that the Permian-Triassic (P-Tr) extinction event may have indeed been caused by massive volcanic eruptions.
The idea was one of the first to be proposed as an explanation, right alongside the formation of the supercontinen... |

The Permian–Triassic (P-Tr) extinction event was the worst mass dying to affect life in all history. It occurred about 250 million years ago, and scientists thought they had a pretty good idea of the factors that caused it. Yet, a new study managed to identify a culprit that also played a role in the extinction... |

A massive extinction event that occurred at the end of the Triassic Period still has researchers baffled. It represents one of the most mysterious mass dyings in the history of the planet, and some believe that it was caused by an asteroid. Scientists are currently looking for a potential impact crater.

For nearly 200 million years, dinosaurs reigned supreme. They were spread out across most locations on the planet, and there were no creatures that could challenge their domination except, of course, other dinosaurs.
