Langental Formation

The Langental Formation, also spelled as Langetal Formation, is a Late Eocene (Bartonian to Priabonian) geologic formation cropping out in the Sperrgebiet, ǁKaras Region of southwestern Namibia. The siltstones and sandstones of the formation were deposited in a shallow marine environment.[1] The Langental Formation was deposited under hot and humid conditions. The formation overlies the Silica Beds unit and is overlain by the Blaubok Conglomerate.[2] The Langental Formation provides many fossil invertebrates and fish.
