Also known as ETE Locality 1131, Mpesida, Baringo, Mpesida beds,
Where: Kenya (0.8° N, 35.8° E: paleocoordinates 0.5° N, 35.2° E)
When: Mpesida Formation, Messinian (7.2 - 5.3 Ma)
• ETE dating method: absolute, ETE age comment: Max age = 7.3-6.9 Ma; Min age = 6.20 +/- .19 Ma radiometric intage_max, radiometric intage_min
•
•Jacobs et al. 2002: Single-crystal, laser-fusion, 4 0 Ar/3 9 Ar dates from a capping trachyte flow as well as tuffs just below the lava contact indicate an age of greater than 6ยท37 Ma for the fossil material.
Environment/lithology: fluvial-lacustrine; lithology not reported
•
•Jacobs et al. 2002: Preserved anatomical features of the fossil wood as well as estimated tree heights suggest a wet, lowland rainforest in this portion of the rift valley. Stable isotopic analyses of fossil enamel and paleosol components indicate the presence of more open habitats locally.
