Kaloma (Miocene of Kenya)

Also known as ETE Locality 898, Kaloma,

Where: Kenya (0.1° N, 34.6° E: paleocoordinates 0.8° S, 32.9° E)

When: Maboko Formation, Langhian (16.0 - 13.8 Ma)

• ETE dating method: composite, ETE age comment: Max age = ~17 Ma based on biostratigraphy. Min age = 11.8 +/- 1.0 my (K/Ar date on Majiwa phonolite) radiometric intage_min

•From Mayr et al. 2014: The Maboko Formation originated about 14-15 million years ago (Feibel and Brown, 1991; Retallack et al., 2002; Geraads et al., 2012); its age thus corresponds with the level MN5 of the European mammalian stratigraphy (Daams et al., 1999).
