Also known as "Elizabethfeldern" (Savage, 1965), Sperrgebiet, E-Feld, Tortoise Site
Where: Karas, Namibia (27.0° S, 15.3° E: paleocoordinates 27.9° S, 12.8° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Elisabeth Bay Formation, Early/Lower Miocene (23.0 - 16.0 Ma)
• The fossiliferous beds were assigned to the Elisabeth Bay Formation by Greenman (1966, unpubl. MSc thesis) but this unit, as originally defined, is penetrated by a major unconformity comprising a hiatus of about 15 Ma (Pickford & Senut, 1999, p. 61 & 76). The name Elisabeth Bay Formation here refers only to the lower, fluvial part of the series which is of Lower Miocene age (Pickford & Senut, 1999, p. 76).
• group of beds-level stratigraphic resolution
Environment/lithology: fluvial; red siltstone and green, yellow sandstone
Size classes: macrofossils, mesofossils
Collected by E. Stromer, M. Pickford, B. Senut in the 1920s, 1990s, 2000s
• The squamate material listed by Rage (2008) was collected by Martin Pickford and Brigitte Senut in the course of the Namibia Paleontology Expedition (NPE) in the 1990s and 2000s and is reposited in the Geological Survey of Namibia in Windhoek.
