The Elisabeth Bay Formation, alternatively spelled as Elizabeth Bay Formation, is an Early Miocene ( Aquitanian to Burdigalian, around 21 Ma) [1] geologic formation in the Sperrgebiet, ǁKaras Region of southwestern Namibia, overlying the Blaubok Conglomerate. [2] The freshwater green and red siltstones, sandstones, intercalations of conglomerates and claystones of the formation were deposited in a fluvial environment, [3] infilling a paleovalley incised during the Oligocene low sea stand, which backfilled during the Burdigalian marine transgression. [1] The Elisabeth Bay Formation provides many fossil mammals, snakes and other reptiles.
The following fossils are reported from the formation: [4] [5] [6]
