Also known as USGS 14872

Where: Santa Barbara County, California (34.9° N, 120.3° W: paleocoordinates 34.6° N, 118.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tinaquaic Sandstone Member (Sisquoc Formation), Messinian to Messinian (7.2 - 3.6 Ma)

• The Sisquoc Formation contains two principal lithologic facies: a fine-grained basin facies ( Todos Santos Claystone mbr) consisting chiefly of diatomaceous mudstone and a marginal sandstone facies ( Tinaquaic sandstone mbr). The basin facies of the Sisquoc Formation overlies the Monterey Formation without discordance. A maximum thickness of 5000 ft is estimated from the subsurface, although the maximum exposed thickness of the formation is 3000 ft. AGE: Revised to Messian-Zanclean consistent with EPICC stratigraphic revision.
