PC1 (SM) - 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.
