Elisabeth Bay Formation (Namibia) | |
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.
