Also known as CIT 389

Where: California (34.6° N, 118.7° W: paleocoordinates 34.5° N, 117.8° W)

• coordinate based on nearby landmark

When: Ridge Formation, Piacenzian (3.6 - 2.6 Ma)

• A more detailed account of the Ridge basin and its sediments was given by Eaton (1939). These shales fall into Eaton's Division II, a thick series of deposits probably of brackish-water and lucustrine origin, and tentatively referred to him to the Pliocene.

Environment/lithology: marine; shale
