Seabird Crevice, Layer II,5, Tinian (Holocene of Northern Mariana Islands)

Where: Northern Mariana Islands (15.0° N, 145.7° E: paleocoordinates 15.0° N, 145.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Holocene (0.0 - 0.0 Ma)

• The two sediment Layers at Seabird Crevice are loose, rubbly, poorly stratified, and poorly differentiated from each other. The surface and Layer I at Seabird Crevice contained historic materials from World War II (gas mask parts, rusted iron, glass, ammunition, unexploded grenade). Seabird Crevice yielded no pottery or other evidence of prehistoric human occupation.

• bed-level stratigraphic resolution

Environment/lithology: fissure fill; lithology not reported

Size class: macrofossils
