Where: Santa Cruz County, California (37.0° N, 122.0° W: paleocoordinates 34.6° N, 117.2° W)

• coordinate based on nearby landmark

When: Santa Margarita Formation, Tortonian (11.6 - 7.2 Ma)

• correlative with the Towsley Formation, 10-12 Ma (Whitmore & Barnes, 2008); age after Fordyce & Marx (2013)

•

•The horizon of the Santa Margarita Formation that yielded UCMP 108558 likely dates to about 10–9 Ma, based on its associated mammal fauna [173: 26-27]. Together, these occurrences indicate an approximate age range of 10.0– 5.3 Ma. (Marx & Fordyce, 2015)
