Chance discovery of 365-million-year-old fossil reveals new species - The large fish, spanning nearly a metre on the lake bed ...

In 2015, two members of the Blue Beach Fossil Museum in Nova Scotia found a long, curved fossil jaw, bristling with teeth.

Extended periods of marine anoxia — a lack of oxygen in the water — characterized the Late Devonian Mass Extinction. The two most pronounced periods are known as the Kellwasser event, which occurred ...

TD: What makes the late Devonian, 370 million years ago, a particularly interesting fossil period is that there was such a wide diversity of basic kinds of fish in the world, many more basic kinds ...

This fish, measuring up to 9 feet (2.7 meters) long, is the largest bony fish on record from the Late Devonian (383 million to 359 million years ago) and was predatory, prompting researchers to ...

The expansion of land plants during the Late Devonian contributed to the marine mass extinction. Communications Earth & Environment , 2023; 4 (1) DOI: 10.1038/s43247-023-01087-8 Cite This Page : ...

Oxygen gradually increased in the oceans from the late Devonian through the end of the Paleozoic. Klug says that he’s happy that his work has sparked this new analysis.

Indeed, the discovery of even a few plutonium-244 atoms in late Devonian fossils would be corroborating evidence for the supernova hypothesis. There are other extinction events that occurred earlier ...

The late Devonian extinction, about 370 million years ago, is one of the 'Big Five.' It killed up to 80 percent of species, obliterating the lavish Devonian coral reef ecosystem.
