Site 16 (LACMIP 363), Calico Hills (Miocene of the United States)

Where: California (34.9° N, 116.8° W: paleocoordinates 34.1° N, 111.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Calico Member (Barstow Formation), Hemingfordian (20.4 - 16.0 Ma)

• Overlying fine-grained lacustrine beds (here referred to as the Calico Member of the Barstow Formation) are bracketed between ca. 19 and 16.9 Ma, and are thus older than the type section of the Barstow Formation in the Mud Hills. Several 17.1–16.8 Ma calc-alkaline dacite domes intrude the Calico Member.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified, nodular, brown shale

• Laminated brown-weathering shale including four beds of nodules

Size classes: macrofossils, mesofossils

Preservation: replaced with calcite, replaced with silica, replaced with other
