• coordinate stated in text

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

•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)

• formation-level stratigraphic resolution

Environment/lithology: offshore shelf; limestone

• shallow mid shelf to inner shelf
