Where: Kenya (0.5° S, 34.0° E: paleocoordinates 1.6° S, 31.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Burdigalian (20.4 - 16.0 Ma)

Environment/lithology: dry floodplain; lithified lithology not reported

• From paleosols

Size classes: macrofossils, mesofossils

Preservation: replaced with calcite

Collected by Dr. and Mrs. Leakey; reposited in the BMNH, MCZ
