The Sioux believe that earth has a history of four distinct ages. These events occurred during the Age of Rock. This portrayal of the thunderbirds may have been influenced by associations of fossils of the Cretaceous pterosaur 931:

fossils to summon bison herds. When used this way, the fossils are called "buffalo-calling stones" or Iniskim. This practice derives from the complex shapes of the fossil's internal structure, which can sometimes bear shapes resembling buffalo. Iniskim have been discovered in South Dakota
505:, central and eastern South Dakota was still covered by the sea. The uplift responsible for the Black Hills continued to elevate their topography. As the Cenozoic continued, the sea shrank away from the state. In its place, grasslands formed and were roamed by herds of grazing mammals. 902:. Some of the fossils were so precariously located that the excavators had to use block and tackle to lower the fossils down from the tops of "slender pinnacles". The fossils were preserved in channel sandstones that had received little scientific attention prior to the expedition. 905:
In June 1947, South Dakota School of Mines sent another expedition into the Badlands. They uncovered a wide variety of fossils preserved in the Oligocene White River Formation. Among the creatures discovered were rhinoceroses, saber-toothed cats, giant pig-like animals,

However, one South Dakotan individual was 6–7 meters (20–23 ft) long. 1838: 2043: 1948: 1898: 2028: 2008: 1973: 1853: 1808: 1803: 2103: 2018: 1998: 1983: 1833: 1702: 2113: 2108: 2073: 2063: 2058: 2048: 1988: 1963: 1958: 1938: 1913: 1893: 1888: 1868: 1823: 1798: 2093: 2053: 2003: 1943: 1933: 1923: 1918: 1863: 1858: 1793: 1788: 2098: 2088: 2078: 2068: 2033: 2023: 2013: 1993: 1968: 1908: 1903: 1883: 1878: 1843: 1828: 1818: 1813: 354: 2083: 1978: 1953: 1928: 1848: 1873: 2134: 508: 1695: 2162: 2152: 1715: 1688: 1387: 945:
