Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period:Paleogene Epoch:Oligocene
Stage:Chattian 10 m.y. bin:Cenozoic 4
Key time interval:Chattian
Age range of interval:28.10000 - 23.03000 m.y. ago
Stratigraphy
Formation:Ettrick
Stratigraphic resolution:group of beds
Stratigraphy comments: "Interestingly, a tooth of the Oligocene shark Carcharodon angustidens. collected at Tailem Bend in 1936, has the same dark preservation as the Metasqualodon and Hexanchus teeth, and other shark teeth from reducing sediments, and adds support for the provenance of Metasqualodon being the Ettrick Formation." (Pledge & Rothausen, 1977). Associated plankton include Turborotalia euapertura, Guembelitria triseriata and Chiloguembelina cubensis, suggesting a Late Oligocene (P21 Zone) age (Gallagher & Gourley, 2007). Metasqualodon teeth likely came from the upper part of the unit (Pledge & Rothausen, 1977).
Lithology and environment
Primary lithology:glauconitic,gray,green marl
Includes fossils?Y
Lithology description: Described as "yellow calcareous clay" but unit is actually a greenish-gray glauconitic marl (yellowish calcareous clay is the overlying Miocene Mannum Fm).

Taphonomy
Modes of preservation:body,original phosphate
Size of fossils:macrofossils
Disassociated minor elements:many
Collection methods and comments
Collection methods:surface (in situ),field collection

Taxonomic list comments:Sanger lists an associated invertebrate fauna, but it may have been derived from a different unit (Pledge & Rothausen, 1977) and the identifications are outdated and questionable.
