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.[https://paleobiodb.org/classic/displayStrata?geological_group=&formation=Langetal&group_formation_member=Langetal Langetal Formation] at Fossilworks.org The Langental Formation was deposited under hot and humid conditions. The formation overlies the Silica Beds unit and is overlain by the Blaubok Conglomerate.Dauteuil et al., 2018, p.6 The Langental Formation provides many fossil invertebrates and fish.
