Foxen Canyon (USGS 14998) - #35 (Woodring & Bramlette, 1950) (Miocene to of the United States)

Also known as USGS 14998

Where: Santa Barbara County, California (34.8° N, 120.2° W: paleocoordinates 34.4° N, 117.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tinaquaic Sandstone Member (Sisquoc Formation), Late/Upper Miocene to Late/Upper Miocene (11.6 - 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

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified, medium-grained, coarse, calcareous sandstone

• Medium-grained to coarse-grained sandstone with grit and calcareous beds. Fines upsection.

Size class: macrofossils

Preservation: mold/impression, replaced with phosphate

Reposited in the USGS

Collection methods: quarrying,

• Presumably reposited in UGGS collections...not specified.
