black limestone
The Black Crow Limestone is an Early Eocene (Late Ypresian to Early Lutetian) geologic formation in the Sperrgebiet, ǁKaras Region of southwestern Namibia. The limestones of the approximately 10 metres (33 ft) thin formation were deposited in a lacustrine to paludal environment. The formation provides many fossil mammals and amphibians, reptiles, fresh water snails and fish.
