Where: California (34.5° N, 118.2° W: paleocoordinates 34.5° N, 118.2° W)

When: Middle Pleistocene (0.8 - 0.1 Ma)

• Specimens at La Brea mostly range from 11,500 to 35,000 years old. One of the older pits, pit 77, has a mean calibrated age of 35,370, while a younger pit, pits 61/67, has a mean calibrated age of 11,581 before present. Many other pits fall in between these dates, however, most seem to occur between 20,000–29,000 years ago
