New uranium-lead dating of zircons from Oklahoma’s buried Ames impact structure points to a Late Devonian age near 370 ...

Research indicates that the Ames impact structure may have formed during the Late Devonian period. This finding challenges earlier beliefs connecting the structure to the Ordovician Meteor Event.

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 ...

According to a recently published study in Meteoritics & Planetary Science, researchers dated zircon crystals from the site and found that the Ames crater likely formed about 370 ...

Scientists discovered that ancient reef-building stromatoporoids survived the Late Devonian extinction, contrary to previous beliefs, and continued to thrive. The findings reveal how these organisms ...

At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts ...
