Also known as USGS loc. 3772
Where: Kern County, California (35.5° N, 119.8° W: paleocoordinates 34.1° N, 111.6° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Wygal Sandstone Member (Temblor Formation), Late/Upper Oligocene (28.4 - 23.0 Ma)
• STRATIGRAPHIC RELATIONS: From Wygal Sst Mbr which regionally overlies the Cymric Shale and is overlain by the Santos Shale of the lower (type) Temblor Fm (Late Oligocene-Middle Miocene). Collection from base of member, where it unconformably overlies the Eocene Point of Rocks Sandstone. THICKNESS: From horizon 6 ft thickness within member that ranges between 20 andf 40 ft in thickness. AGE: Late Oligocene; lower Zemorian foraminiferal staghe, Blakeley molluscan stage. STRATIGRAPHIC POSITION: Presumably near base of member near contact with Point of Rocks Sandstone.
• bed-level stratigraphic resolution
Environment/lithology: transition zone or lower shoreface; lithified, shelly/skeletal sandstone
Size class: macrofossils
