K:See under individual entries.
L:Upper Bed I: 1-8-1-7 Myr on basis of 57 K/Ar dates of tuffs and pumice distributed throughout Bed. Bed II: 1-7-1-15 Myr on basis of K/Ar date of Tuff IIa, palaeomagnetic data and relative stratal thickness. Lemuta Member: c. 1-6 Myr. Bed III/IV: 1-15-0-6 Myr on basis of palaeomagnetic data and relative stratal thickness. Masek Beds: 0-6-0-4 Myr on basis of palaeomagentic data and K/Ar dating. Nudutu Beds: Lower Unit 400,000-60,000 BP Upper Unit 60,000-32,000 BP both on basis of C14, amino-acid racemization and geochemical data(e.g. alteration of napheline). Naisiusiu Beds: > 22,000 - < 15,000 BP on basis of C14 dates obtained from calcretes and bone collagen. R.L.Hay 1976. The correlation of Magnetic epochs etc. is shown in Fig.4.
M:See under individual entries.
U:Site are given in alphabetidal order under headings of the various Beds. Beds themselves are in the order I, II, III/IV, Masek, Ndutu, Naisiusiu and Unknown. The following list is intended to facilitate the location of individual hominids.
