LACMIP 435, San Pedro (Pleistocene of the United States)

Also known as Miraleste Canyon

Where: Los Angeles County, California (33.8° N, 118.3° W: paleocoordinates 33.8° N, 118.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lomita Marl Formation, Middle Pleistocene (0.8 - 0.1 Ma)

• AGE: Listed as "Late Pliocene" in comments and "Piacenzian" in maximum age; reassigned to Middle Pleistocene, which is the accepted age of the Lomita Marl of modern workers; some 1960s-1970s research suggested a middle Pliocene age, but this is no longer considered valid (Hendy, 2021).
