Chota Nagpur Plateau has the remains of an old fort belonging to the Nagavanshis. The Chhota Nagpur Plateau is a continental plateau—an extensive area of land thrust above the general land. The plateau has been formed by continental uplift from forces acting deep inside the earth. The Gondwana substrates attest to the plateau's ancient origin. It is part of the Deccan Plate, which broke free from the southern continent during the Cretaceous to embark on a 50-million-year journey that was violently interrupted by the northern Eurasian continent. The northeastern part of the Deccan Plateau, where this ecoregion sits, was the first area of
Kaiparowits Plateau identified in the Kaiparowits Formation. As recently as 2007, the characterization of an unusual species of "Gryposaurus", a duck-billed dinosaur, was announced. Fossils of the giant crocodilian Deinosuchus have also been found. Early settlers of the region mined certain parts of the plateau for coal in the 1870s and 1880s. The Spencer mine opened in 1913, reportedly to fuel gold mining activities along the Paria River. In 1965, the Southern California Edison Company proposed the construction of a 3000 megawatt coal-fired generation plant within the Kaiparowits Plateau.
