The Carters Limestone is a geologic formation in Tennessee. It preserves fossils dating back to the Ordovician period. [1] [2] [3] The Carters contains abundant invertebrate fossils, including corals, stromatoporoids, brachiopods and bryozoans, mollusk (gastropods, bivalves and orthoconic cephalopods) and trilobites. Trace fossils also occur. The unit has several volcanic ash (bentonite) beds and is known to have isolated reef development.

Fossil Cycad National Monument was a national monument in the U.S. state of South Dakota beginning in 1922. The site contained hundreds of fossils of the cycad-like bennettitalean plant Cycadeoidea, one of the world's greatest concentrations.

It is located in northwestern Fall River County, on U.S. Route 18, northeast of the city of Edgemont.
