Also known as Ileret

Where: Kenya (4.3° N, 36.3° E: paleocoordinates 4.2° N, 36.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: KBS Member (Koobi Fora Formation), Gelasian to Gelasian (2.6 - 0.8 Ma)

• from "1.5 m below the Main Ileret Caliche" (boundary between the KBS and Okote members)

•above the KBS Tuff (1.869 +/- 0.021 Myr) and below the Lower Ileret Tuff (1.527 +/- 0.14 Myr), but much closer to the latter and well above an ash correlated with a Shungura Formation ash that is just above the Morutot Tuff (1.607 +/- 0.019 Myr); estimated age 1.55 +/- 0.01 "assuming constant sedimentation rates"

• bed-level stratigraphic resolution

Environment/lithology: fluvial; coarse-grained, concretionary, calcareous sandstone

Size class: macrofossils

Collected by F. K. Manthi in 2000
