Etjo Sandstone

The Etjo Sandstone is an Early Jurassic geologic formation in northern Namibia. The formation overlies the Omingonde Formation in the Waterberg Basin and the Doros and Gai-As Formations in the Huab Basin and has a total thickness of 140 metres (460 ft).^[1] Fossil theropod tracks of Prosauropoda indet., Theropoda indet., Tetrapodium elmenhorsti, Saurichnium anserinum, S. damarense, S. parallelum and S. tetractis have been reported from the formation, deposited in an aeolian environment.^[2][3]
