Ever since the first dinosaur fossils were identified in the 19th century, scientists have been trying to figure out why ...

Some of these took place during the Mesozoic Era. Early Mesozoic Mass Extinction Event. Trilobites were wiped out during the Great Dying after having lived on Earth for more than 300 million years.

Deeper in time, a mass extinction event that ended the Devonian Period, a geological era when life thrived on land for the first time, was also attributed to a hyperthermal event likely triggered ...

Patterns of Extinction: The species alive today are only a tiny fraction of all those that have ever lived. The vast majority of species in the history of the planet have become extinct.The fossil ...

This series of mass extinctions during the Devonian period eventually eliminated about 75 percent of life. However, some of Earth’s oldest fish called coelacanths make it out unscathed.

By simulating the movement of two continent-sized Big Lower-Mantle Basal Structures, or BLOBs, researchers may have uncovered ...

Mass extinctions have occurred five times in Earth’s history, each resulting in the loss of at least 75% of species. These events are often linked to catastrophic occurrences such as volcanic ...

To some of us this is what they know, this is all they know. The five mass extinctions of the ancient past were caused by natural calamities—volcanoes, and an asteroid.

The K-Pg extinction is the most recent of five events in Earth’s history that scientists consider mass extinctions, defined by paleontologists as events where more than 75 percent of species vanish ...

A mass extinction at the beginning of the period, caused by massive volcanic outpourings in what’s now Siberia, spurred rapid global warming, changes in atmospheric oxygen levels, and other ...
