Where: Philippines (15.2° N, 121.0° E: paleocoordinates 15.2° N, 121.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tartaro Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• STRATIGRAPHIC RELATIONS: From Tartaro Fm, which lies Makapilapi Fm (Late Miocene) and the Alat Conglomerate Mbr of the Guadalupe Fm (Pleistocene). THICKNESS: 150 m for fm. AGE: Pliocene according to Table 1 of Kanno et al. (1982), lying between Late Miocene (Makapilapi Fm) and Pleistocene Alat Cgl. Mbr. Biostratigraphic data presented in text (Table 2) suggests a Late Miocene age. Gonzales et al. (1971) place the Tartaro Fm in the Pliocene-Pleistocene) based on benthic foraminifera. Author, however follows Shuto's (1969, 1971) molluscan biostratigraphy and correlates the Tartaro Fm to the Late Miocene. STRATIGRAPHIC POSITION: Unknown position within formation.
