| Basis of coordinate: | stated in text | ||
| Geographic resolution: | outcrop |
Time
| Period: | Quaternary | Epoch: | Pleistocene |
| Stage: | Late/Upper Pleistocene | 10 m.y. bin: | Cenozoic 6 |

Stratigraphy
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: 127-117 ka age (Marine Isotope Substage 5e) for corals that were directly dated from localities SDMNH 0633 (UCMP D1547), 0644, and 2465 (Muhs 1994); dates are inferred to apply to the rest of the Discovery Point Formation, but its not clear that this locality is Discovery Point Formation. | |||||
Lithology and environment
| Primary lithology: | lithified conglomerate |
| Secondary lithology: | "limestone" |
| Lithology description: coquina; Discovery Point Formation: coarsely clastic sediments that grade laterally from conglomerate, locally with pebbles of volcanic origin, to a biostrome formed chiefly of coral fragments and mollusk shells. | |
| Environment: | perireef or subreef |
| Glacial or sequence phase: | interglacial |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils,microfossils |
