NB 9446 - Togopi Fm (Pliocene to of Malaysia)

Where: Malaysia (5.5° N, 117.0° E: paleocoordinates 5.5° N, 117.1° E)

• outcrop-level geographic resolution

When: Togopi Formation, Pliocene to Pliocene (5.3 - 0.0 Ma)

• STRATIGRAPHIC RELATIONS: From Togopi Fm. Unknown lithostratigraphic relationships. THICKNESS: Unit of unknown thickness. Collections assumed to be from individual beds. AGE: Debated. Cox (1948) suggested a Pliocene, if not Late Miocene age; Nuttall (1961) suggested Quaternary, but possibly Pliocene; Nuttall (1965) suggested a Plio-Pleistocene age. A Pliocene-Pleistocene age is assigned here. STRATIGRAPHIC POSITION: From unknown position within unit.

• bed-level stratigraphic resolution

Environment/lithology:

• ENVIRONMENT: From rather shallow water, possibly in carbonate setting.
• SPECIFIC LITHOLOGY: Lithology not stated in text. LITHIFICATION: Unknown lithology.

Size class: macrofossils

Collection methods: COLLECTOR: Collected by N. S. Haile (c. 1950's). REPOSITORY: Unknown. NB....may well stand for some repository.
