Basis of coordinate:stated in text
Geographic resolution:outcrop
Time
Period:Paleogene Epoch:Oligocene
Stage:Chattian 10 m.y. bin:Cenozoic 4
Key time interval:Chattian
Age range of interval:28.10000 - 23.03000 m.y. ago

Stratigraphy
Formation:Milburn Limestone
Stratigraphy comments: 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)
