Stratigraphy
Formation:Ceru Mainsjie
Stratigraphic resolution:group of beds
Stratigraphy comments: Collection derived from two horizons within the Ceru Mainsjie Formation a Punt Kanon. NMB 12910 is a sandstone bed (40 cm thick) and is about 20 m stratigraphically below NMB 12911. Considered to be Early Eocene by Altena (1941). Foraminiferal evidence of Keyzer (in Schaub 1948) suggested a Late Eocene age. Hermes (1968) used planktonic foraminifera to indicate a upper Middle Eocene age. Molluscan biostratigraphy excludes an Early Eocene age, though definately point to the Eocene. Taxa are most similar to those of Late Eocene age from Peru. Jung suggests therefore that the age is Late Eocene or somewhat older, but later indicates that is probably late Middle Eocene age. Therefore the enterer (A. Hendy) assigns a Bartonian age.

Includes fossils?Y
Lithology description: Calcareous clay and silt and subordinate calcareous sandstone and conglomerate. Specifically mentions a brownish-green sandstone for this collection.
Environment:marginal marine indet.
Geology comments: Brackish water influence, although co-occuring with many normal salinity taxa.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection methods:selective quarrying,field collection
Reason for describing collection:general faunal/floral analysis
Museum repositories:NMB
Collection method comments: Collections reposted in the Naturhistorisches Museum Basel (NMB). Collected by P. Jung (1971).
Taxonomic list comments:Exhaustive for Mollusca, although the authors suggest that careful collecting would yield further taxa. Eocene fossils from region have been reported previously by Hummelinck (1940) and mentioned by Molengraaf (1929), Rutsch (1939), and Schaub (1948).
