Fossil Types
Some fossil bivalves and worm tracks are found in the Deadwood formation in Paleozoic era strata.
Many clam and oyster fossils can be found in the limestone formations of the Black Hills in Paleozoic and Mesozoic era strata. Occasionally belemnite (resembles a squid) parts can also be found.
Petrified wood can be observed near the former Elk Creek campground. In the extreme southern Black Hills, cycad fossils were an important resource of the now defunct Cycad National Monument north of Edgemont. Excellent specimen of these and other fossils are on exhibit at the South Dakota School of Mines and Technology Museum in Rapid City and in the Black Hills Museum of Natural History in Hill City.
One of the largest mammoth excavation sites in the region is located near Hot Springs. The site contains some beautifully preserved skeletons and is completely enclosed to enhance touring and educational activites. At least two mammoth species have been identified there.
