WK 4077 - Togopi Fm (Pliocene to of Malaysia)

Where: Malaysia (5.5° N, 117.0° E)

• Paleocoordinates: 5.3° N, 117.4° E (Wright 2013)

• 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 Wenk. Most of the Wenk collection is apparently now lost (in transit). REPOSITORY: Unknown.
