Also known as ETE Locality 1391, Peninj-Middle Zone,
Where: Lake Natron Basin, Tanzania (2.3° S, 36.0° E: paleocoordinates 2.4° S, 35.9° E)
When: Middle Zone Member (Humbu Formation), Calabrian (1.8 - 0.8 Ma)
• ETE dating method: absolute, ETE age comment: Was-Mbugu olivine basalt smpls(1964&1969 Isaac) radiometric intage_max, radiometric intage_min
•Was originally under Hubu Formation. Base of formation is about ~1.75Ma, the Main Tuff is ~1.19+/-0.03Ma. The top of the Peninj Group is about 1.01+/-0.03Ma, therefore, the upper dsands are ~1.2-1.1Ma (Deino et al. 2006)
Environment/lithology: lacustrine; tuff
Size class: macrofossils
Collection methods: surface (in situ)
