Ancient Coral Reefs Corals appeared about 475 million years ago as a result of the association of jellyfish-like animals and single-celled plants within the same compound organism. Thirty million years later, reef-like structures dominated by coralline skeletons were widespread, and have been particularly well studied on Manitoulin Island, Ontario. Here, several kilometres from an ancient shoreline, many kinds of corals grew in warm water about a metre below the le ...

New report on Jurassic Reefs in Alabama Jurassic Reefs of the Smackover Formation in South Alabama is a new publication of the Geological Survey of Alabama (Circular 195, by David Kopaska-Merkel), which describes fossil reefs that form an important part of the Smackover Formation, Alabama's most prolific hydrocarbon-producing unit. The fossil reefs of the Smackover Formation are found primarily in Mobile, Monroe, Conecuh, and Escambia Counties. The reefs are located in ancient depositional ...

Localities of the Cambrian: The White-Inyo Mountains Along the California-Nevada border north of Death Valley, the White Mountains, the Inyo Mountains, and associated ranges present one of the most important and best-known Late Proterozoic to Cambrian sections in the United States. Starting with the unfossiliferous Precambrian rocks of the Wyman Formation, paleontologists can work their way through a complete section that documents the appearance of various animals and protists, starting ab ...
