Where: Kenya (4.2° N, 36.4° E: paleocoordinates 4.1° N, 36.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Burgi Member (Koobi Fora Formation), Gelasian (2.6 - 1.8 Ma)

• Minimum age= 1.88 Ma (KBS Tuff, K/Ar and Ar/Ar dating).

•Maximum age based on faunal and geological data from the Upper Burgi indicating that it is no older than 2.0 Ma

•

•Approximately at the same stratigraphi level as KNM-ER 1470 (hominid skull)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; poorly lithified, silty sandstone

Size class: macrofossils

Preservation: original phosphate, replaced with calcite

Collection methods: surface (float), surface (in situ), mechanical,

• All bone fragments were collected 10 x 10 m squares 20 m apart (on a grid) and sorted into identifiable and unidentifiable at the sampling site. Identifiable fragments were bagged and taken to the Kenya National Museum for identification. "Good" specimens were incorporated into the taxonomic collections at KNM, the rest were stored in the basement of KNM.
