Mammals switched to daytime activity after dinosaur extinction
Mammals only started being active in the daytime after non-avian dinosaurs were wiped out about 66 million years ago (mya), finds a new study...
Research provides unique insight into extinction dynamics in late Triassic
One of the most exciting discoveries that paleontologists can make is finding the causal relationship between the extinction of ancient creatures and the environmental...
Lost mountains in the Karoo reveal the secrets of massive extinction...
Fossil records near the lost Gondwanides mountains show that the Permian-Triassic extinction started 1 million years prior to what was previously believed.

Mass extinctions led to low species diversity, dinosaur rule
Two of Earth's five mass extinction events -- times when more than half of the world's species died -- resulted in the survival of...
Siberian volcanic eruptions caused extinction 250 million years ago
A team of scientists has found new evidence that the Great Permian Extinction, which occurred approximately 250 million years ago, was caused by massive...

But...
Size not important for fish in the largest mass extinction of...
Understanding modern biodiversity and extinction threats is important. It is commonly assumed that being large contributes to vulnerability during extinction crises.
However, researchers from the...
Large volcanic eruption may have caused the first mass extinction
Researchers in the USA and Japan say they may have found the cause of the first mass extinction of life.
