Where: South Otago, New Zealand (46.1° S, 170.0° E: paleocoordinates 52.3° S, 175.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Milburn Limestone Formation, Chattian (28.1 - 23.0 Ma)

• Waitakian, Oligocene; the Oligocene portion of the Waitakian is Chattian

•

•The precise stratigraphic context of OU 11573 is currently unknown, but likely falls within the early Waitakian (Oligocene, 25.2–23.0 Ma [2]). This estimate is supported by s strontium date of 23.8 ± 0.7 Ma for the horizon that yielded OU 22545. (Marx & Fordyce, 2015)
