Time
| Period: | Quaternary | Epoch: | Pleistocene |
| Stage: | Late/Upper Pleistocene | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Late/Upper Pleistocene | ||
| Age range of interval: | 0.12900 - 0.01170 m.y. ago | ||
| Age estimate: | 11170 ± 130 YBP (14C) |
Stratigraphy
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "very late Rancholabrean; two carbon dates on Bison bone are 9990 +/ 20 ybp and 11,170 +/- 130 ybp; older date is on better preserved material | |||||
Lithology and environment
| Primary lithology: | fine,pebbly,shelly/skeletal sandstone |
| Lithology description: "just below the exposed surface [underwater] of a stratum of rubble composed of rocks, wood, and shells" overlying "a stratum of clean, fine quartz sand containing pebbles, cobbles, and numerous gastropod shells" plus a "Bison right femur fragment"; remaining Bison material is thought to have originally been buried in the quartz sand | |
| Environment: | pond |
| Glacial or sequence phase: | late glacial |
| Geology comments: general environment "consisted of scattered ponds which periodically collected rain and runoff water... Perhaps the Bison was killed at the water hole and butchered behind the [nearby] boulders" | |
