Packard's Hill (Pliocene to of the United States)

Where: Santa Barbara County, California (34.4° N, 119.7° W: paleocoordinates 34.3° N, 119.1° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Santa Barbara Formation, Late/Upper Pliocene to Late/Upper Pliocene (3.6 - 0.8 Ma)

Environment/lithology: marine; poorly lithified, yellow, calcareous sandstone

• The hill consists of layers of fine, soft, light yellow sand and marl, which is hardened in places by the lime leached from shells. The clip of the beds is nearly due south at an angle of 15° . The hardened strata are darker colored than the softer beds, and as a rule are more fossiliferous. The fossils in the soft strata are very fragile, but by using care some fine specimens may be obtained from them.

Size class: macrofossils

Reposited in the USNM
