Geography

Country:	Namibia	State/province:	Sperrgebiet
Coordinates:	27.4° South, 15.4° East (view map)
Paleocoordinates:	36.2° South, 11.5° East (Wright 2013)
Basis of coordinate:	estimated from map
Geographic resolution:	outcrop

Time

Period:	Paleogene	Epoch:	Eocene
Stage:	Priabonian	10 m.y. bin:	Cenozoic 3
Key time interval:	Priabonian	Nannofossil zone:	NP 19-20
Age range of interval:	37.71 - 33.9 m.y. ago

Stratigraphy

Formation:	Langental Beds
Stratigraphic resolution:	group of beds
Stratigraphy comments: The marine beds are only about 4 m thick. The age can be narrowly defined by the range overlap of Discoaster saipanensis and Isthmolithus recurvus. The former ranges from the middle to upper Eocene and the latter from upper Eocene to lower Oligocene. They co-occur only in the NP 19 and NP 20 zones of Martini's (1971) biostratigraphic zonal scheme, and only in the I. recurvus subzone of Bukry's (1975) zonal scheme. Informally named "Langental Beds."

Lithology and environment

Primary lithology:	shelly/skeletal,green,yellow poorly lithified calcareous siltstone
Secondary lithology:	concretionary,shelly/skeletal,gray,green,yellow lithified calcareous sandstone
Includes fossils?	Y
Includes fossils?	Y
Lithology description: Concretionary calcareous sandstones and marly sandstones and siltstone. At least one layer of light-brown ferruginous calcirudite occurs near the bottom of the section. This layer contains pebbles, but is predominantly composed of neomorphosed mollusc fragments set in micrite and microspar. The marly sand- and siltstones are mostly pale greenish yellow, poorly consolidated, and calcareous. The calcareous concretionary layers are greyish yellow to pale greenish yellow and are moderately well indurated.
Environment:	shallow subtidal indet.
Geology comments: Members of the nannofossil genus Braorudosphaera are virtually absent in open-ocean deposits, and are thus strong indicators of nearshore environments; Zygrhablithus bijugatus is also most common in nearshore waters. The benthic foraminifera also suggest a normal marine, shallow-water environment.

Taphonomy

Modes of preservation:	body
Size of fossils:	macrofossils,mesofossils,microfossils

Collection methods and comments

Collection excludes:	all macrofossils
