The secret to their longevity could help conservationists better protect species today threatened by extinction.

Utah researchers think they now know how existing crocodiles and alligators were able to survive the last two extinctions.

In its 4.5 billion year history, Earth has undergone five mass extinctions and we are potentially in a sixth era of mass death. Today’s crocodylians are the surviving members of a lineage called ...

Our planet’s first known mass extinction happened about 440 million years ago. Species diversity on Earth had been increasing over a period of roughly 30 million years, but that would come to a halt ...

This allowed time to review species that would have lived around the time of the end-Triassic extinction, about 201 million years ago, and the end-Cretaceous extinction, 66 million years ago.

Discover how crocodiles survived two mass extinctions thanks to their flexible diets and habitats, according to research.

Despite their dominance, once the end-Triassic extinction hit, no non-crocodylomorph pseudosuchians survived. Whereas hyper-carnivore crocodylomorphs appeared to also die off, the terrestrial ...

For scientists and conservationists, knowing how species survive planetary crises can lead to more effective protection of vulnerable species.
