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)
• New total-fusion K-Ar ages indicate that all of the fossiliferous formations that make up the lower part of the Early Miocene Kisingiri sequence in western Kenya at Rusinga Island, Mfwangano Island, and Karungu were deposited during an interval of less than 0.5 million years at c. 17.8 Ma ago.
• bed-level stratigraphic resolution
Environment/lithology: dry floodplain; lithified lithology not reported
Size classes: macrofossils, mesofossils
Preservation: replaced with calcite
Collected by Dr. and Mrs. Leakey; reposited in the BMNH, MCZ
• Holotype and some paratypes deposited in British Museum (Natural History). Other paratypes deposited in MCZ and in the Centre for Prehistory and Paleontology, Coryndon Museum, Nairobi, Kenya.
