| Sammlung | Epoche, Alter | Kommentar zur Sammlung | ||

| "localities I, IV, V, and IX are intercalated with volcanic tuffs... and biotites from these tuffs at Napak I have produced dates of 19.5 +/- 2 Ma and 18.3 +/- 0.4 Ma" after being "adjusted for new constants" but "the younger date is discrepantly low" so an age of "between 19 and 20 Ma" (i.e., Burdigalian) is favored (Rossie and MacLatchy 2006) | ||||

| Buluk | Leakey and Walker (1985) give the same coordinate and say the main locality is a "small exposure" although the original list pertained to an area of "2-3 square miles" | Burdigalian zwischen 15.97 und 23.03 Millionen Jahren |

| "K/Ar dates on a basalt just above the fossiliferous sediments show that the fossils are older than 17.2 Myr" (Leakey and Walker 1985); fossils are from about 15 m within the ~50 m thick Buluk Member according to McDougall and Watkins 1985, who report a series of dates, of which one of 17.2 +/- 0.2 Ma for an immediately overlying basalt is favored | "coarse silt" (Harris and Watkins 1974) or "claystones with coarse sandstone and conglomerate channel fills" (Leakey and Walker 1985) | |||
| U.a. am Fundort ausgegraben: | Noropithecus bulukensis | |||
