Time
| Period: | Paleogene | Epoch: | Eocene |
| Stage: | Priabonian | 10 m.y. bin: | Cenozoic 3 |
| Key time interval: | Priabonian | ||
| Age range of interval: | 37.71000 - 33.90000 m.y. ago |
Stratigraphy
| Formation: | Gehannam | ||||
| Stratigraphy comments: The Basilosaurus locality and the entire open plain surrounding it are in the lower part of the Gehannam Formation, deposited during sea level rise following the Pr-1 low sea stand [31]. The Pr-1 low sea stand marks the Bartonian–Priabonian stage/age boundary marking the transition from the middle to the late Eocene. The closest stratigraphic sections are Amin Strougo’s sections S329 and S340 some 5 km south of WH 10001, where the lower Gehannam Formation is in nannoplankton zone NP17 and in planktonic foraminiferal zone P14 [32]. Combining this evidence, the age of WH 10001 is approximately 37.5 Ma [33]. |
