The Dakota Formation is a geological unit primarily composed of sandstone, shale, and limestone, formed during the Late Cretaceous period, around 100 to 80 million years ago. It is predominantly found in the western United States, particularly in states like Colorado, Wyoming, and South Dakota. The formation is significant for its fossil deposits, including dinosaur remains, and serves as an important source of groundwater and hydrocarbons in certain regions. Its varied lithology reflects diverse depositional environments, including coastal and fluvial settings.
