Black Crow (Eocene of Namibia)

Also known as Sperrgebiet

Where: Sperrgebiet, Namibia (27.4° S, 15.5° E: paleocoordinates 33.7° S, 6.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Lutetian (47.8 - 41.3 Ma)

• bed-level stratigraphic resolution

Environment/lithology: karst; dolomitic, cherty/siliceous limestone

• Pickford et al. (2008) refer the depositional environment to as "kamenitzas", "solution pans, usually circular or oval in plan, with flat bottoms and rounded edges." The rock that underwent solution is a dolomite (Gariep Dolomite, Neoproterozoic).
• fossiliferous freshwater limestones, post-depositionally silicified

Size classes: macrofossils, mesofossils

Collection methods: bulk, acetic, sieve
