Eocliff (Eocene of Namibia)

Also known as Sperrgebiet

Where: Sperrgebiet, Namibia (27.4° S, 15.6° E: paleocoordinates 32.3° S, 7.7° E)

• coordinate estimated from map

When: Bartonian (41.3 - 38.0 Ma)

• Specimens come from multiple limestone blocks, with each one given a number, but all grouped here into one collection

•

•Sallam and Seiffert (2016) argued for a late Oligocene age

• group of beds-level stratigraphic resolution

Environment/lithology: spring; limestone

• partly silicified limestone: The Eocliff deposit formed as a series of coalescent tufa mounds round a hard-water spring at the surface of the ancient topography.

Size class: macrofossils
