Where: Kern County, California (35.1° N, 119.2° W: paleocoordinates 34.1° N, 108.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: San Emigdio Formation (San Lorenzo Group), Late/Upper Eocene (37.2 - 33.9 Ma)
• STRATIGRAPHIC RELATIONS: From San Emigdio Fm San Lorenzo Group, which unconformably overlies the Meagnos and Tejon Fm's (Early-Middle Eocene), and is unconformably overlain by the Pleito Fm (Early Oligocene) of the San Lorenzo Group. THICKNESS: From bed within unit of formation that reaches 200 ft in thicknes. AGE: Late Eocene on the basis of molluscan biostratigraphy. STRATIGRAPHIC POSITION: From middle unit of the formation.
