The Late Devonian mass extinction (roughly 372 million years ago) was one of five mass extinctions in Earth's history, with roughly 75% of all species disappearing over its course. It happened in two ...

Late Devonian brachiopod fossils were preserved as molds in a fine-grained sandstone (Big Creek, Hornell, New York, N 42.364361, W 77.645760). Individual fossil samples like this are the basis for ...

In times of environmental upheaval, how do communities of organisms respond? When entire species are wiped out, do surviving species move in and take over, or do new species immigrate to fill the gaps ...

Rockport Quarry in Alpena, Michigan, looks like a normal fossil-hunting spot until the ground starts telling a much older story. The area is packed with Devonian marine fossils from roughly 390 ...

The Devonian (419.2-358.9 Ma) is the first geological period of the late Paleozoic, spanning about 60.3 Ma from the end of the Silurian, and its beginning is marked by the First Appearance Datum (FAD) ...

The Tentative Lists of States Parties are published by the World Heritage Centre at its website and/or in working documents in order to ensure transparency, access to information and to facilitate ...

Ventral view of Mucrospirifer, a fossil brachiopod, showing the characteristically wing-like shell. This Devonian specimen from Ohio is 3.5cm wide. Brachiopod hard parts have excellent preservation ...

Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass ...
