The Paleozoic Era. From the University of California at Berkeley Museum of Paleontology (UCMP) exhibit. Links to articles on Paleozoic stratigraphy, ancient life, and fossil localities.

The Silurian Period. UCMP exhibit. Links to articles on Silurian stratigraphy, ancient life, fossil localities, and tectonics/paleoclimate.

The Virtual Silurian Reef. An extensive site on Silurian reefs, including basic concepts, distribution of Silurian reefs, reef organisms, biodiversity, Silurian reefs in the field, environmental relations, the history and future of reefs.

The Devonian Period. UCMP exhibit. Links to articles on Devonian stratigraphy, ancient life, and fossil localities.

Falls of the Ohio State Park is located on the banks of the Ohio River in Clarksville, Indiana. The 386-million-year-old fossil beds are among the largest naturally exposed Devonian fossil beds in the world. This site includes information on the history of the fossil beds; a photo album of limestone and fossils; and articles on patch reefs, reef organisms, and more.

The Devonian Great Barrier Reef. Describes a huge Devonian barrier reef in Western Australia. Nice illustrations.

The Devonian Times. The recent discovery of Hynerpeton bassetti has enriched our understanding of how vertebrates colonized the land. Hynerpeton is the first Devonian tetrapod found in North America, and it's one of the oldest tetrapods found anywhere. In addition, the Red Hill site in Pennsylvania where Hynerpeton was discovered has yielded numerous fossils of fishes, invertebrates, and plants, thus providing a window on this important period in evolution.
