- La Formació Dakota, Dakota Formation, (també Dakota Sandstone i Cockrum Sandstone, més formalment el Dakota Group) és una formació geològica composta de roques sedimentàries dipositades en la part oriental del del Cretaci tardà. F.B. Meek i F.V. Hayden,el 1862, li van donar aquest nom per estar situada al llarg del riu Missouri prop de Dakota City, Nebraska. Els estrats consten dipòsits sorrencs marins i ocassionalment dipòsits de torrents. La Formació Dakota és un aqüífer important en algunes zones de les Great Plains. (ca)
- The Dakota is a sedimentary geologic unit name of formation and group rank in Midwestern North America. The Dakota units are generally composed of sandstones, mudstones, clays, and shales deposited in the Mid-Cretaceous opening of the Western Interior Seaway. The usage of the name Dakota for this particular Albian-Cenomanian strata is exceptionally widespread; from British Columbia and Alberta to Montana and Wisconsin to Colorado and Kansas to Utah and Arizona. It is famous for producing massive colorful rock formations in the Rocky Mountains and the Great Plains of the United States, and for preserving both dinosaur footprints and early deciduous tree leaves. Owing to extensive weathering of older rocks during the Jurassic and Triassic, the Dakota strata lie unconformably atop many different formations ranging in age from Precambrian to Early Cretaceous. With a few local exceptions, it is the oldest Cretaceous unit exposed in the northern Great Plains, including Kansas, Nebraska, Iowa, Minnesota, and Wisconsin, as well as the Desert Southwest. It generally consists of sandy, shallow marine or beach deposits with marine-influenced mudflat sediments, and occasional stream deposits. (en)
- Le grès du Dakota (Dakota Sandstone ou Cockrum Sandstone ou Dakota Formation en anglais) est un terme général employé pour parler de formations géologiques mal définies présentes dans les montagnes Rocheuses et les grandes plaines aux États-Unis. Il s'agit de grès qui ont été formés par des dépôts de sédiments sableux durant le Crétacé supérieur lorsque la région était recouverte par une mer peu profonde : la Voie maritime intérieure de l'Ouest.
