The team documented nearly every known Ediacaran animal’s environment, body size, diet, ability to move, and habits. With this project, the researchers sought to disprove the charge that the major ...

Early animals formed complex ecological communities more than 550 million years ago, setting the evolutionary stage for the Cambrian explosion, according to a study by Rebecca Eden, Emily Mitchell, ...

A new study by geobiologists traces the cause of the first known mass extinction of animals to decreased global oxygen availability, leading to the loss of a majority of animals present near the end ...

Waves of extinction have ripped through life on Earth over and over again during its long history. The non-avian dinosaurs were the last to feel the burn, 66 million years ago, but there have been ...

Researchers have gone back in time to find an extinction event that predates all other known events of their kind. The extinction event, which occurred during the Ediacaran Period roughly 550 million ...

Virginia Tech researchers unraveled new evidence that suggests the earliest known mass extinction event on Earth was caused by a drop in oxygen levels about 550 million years ago. This marks the sixth ...
