From the end of the Middle Devonian (382.7 ± 1.6 Ma), into the Late Devonian (382.7 ± 1.6 Ma to 358.9 ± 0.4 Ma), several environmental changes can be detected from the sedimentary record, which …

Devonian extinctions, a series of mass extinction events primarily affecting the marine communities of the Devonian Period (419.2 million to 359 million years ago).

The Late Devonian extinction was a global event that occurred approximately 375 million years ago in which about 70–85 percent of all marine life died out. Rather than occurring in a single episode, this …

Feb 28, 2025 · Devonian reefs like those in Delaware Water Gap National Recreation Area in Pennsylvania and New Jersey were dominated by stromatoporoid, but these reefs were wiped out in …

There are three important extinctions in latter half of the Devonian Period, each separated by about 10 million years. Only one of these, at the end of a time interval called the Frasnian, is normally …

The Late Devonian Mass Extinction, occurring roughly between 375 and 359 million years ago, was one of Earth’s “Big Five” mass extinctions. This event significantly reshaped marine ecosystems globally.

Jan 23, 2021 · Even that paradoxical title seems fitting: The Devonian extinction ravaged Earth on and off for 25 million years, and although it ultimately killed three-quarters of all species, it also cleared …
