Pisonia rockshelter, layer IV-V, Aguiguan (Holocene of Northern Mariana Islands)

Where: Northern Mariana Islands (14.9° N, 145.6° E: paleocoordinates 14.9° N, 145.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• A loose area of the excavation wall that had to be salvaged in such a way that Layers IV and V could not be distinguished. Layers II-IV are pottery-rich, prehistoric cultural deposits spanning more than a millennium. Layer V may be partly pre-human in age, based on a sharp decline in pottery content, lack of charcoal, and scarcity of burned bones.

• bed-level stratigraphic resolution

Environment/lithology: fissure fill; lithology not reported

Size class: macrofossils
