Where: Los Angeles County, California (34.4° N, 118.5° W: paleocoordinates 34.1° N, 117.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Towsley Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)
• STRATIGRAPHIC RELATIONS: From the Towsley Fm, which unconformably overlies Eocene strata, and is overlain by the Pico Fm (Pliocene). AGE: Early Pliocene, on the basis of macrofossil biostratigraphy. STRATIGRAPHIC POSITION: From very small lense of Conglomeratic siltstone in sandstone-conglomerate tongue from about 60 ft below contact with Pico Fm.
• bed-level stratigraphic resolution
Environment/lithology: coastal; poorly lithified, conglomeratic siltstone
Size class: macrofossils
