Abstract
Full Text 		Late Pliocene Faunal Turnover in the Turkana Basin, Kenya and Ethiopia
Anna K. Behrensmeyer, Nancy E. Todd, Richard Potts, and Geraldine E. McBrinn

Supplemental Data

Table 1. Species list and range data for the minimizing approach.

These data were used in constructing the minimizing range chart (Figure 3) and the turnover graph (Figure 4B). The MaxAge dates (*) indicate which taxa would be affected by the alternative date of 2.52 Ma. for the upper Burgi fauna at East Turkana.#Specimens is a minimum estimate; #Loc. exceeds #Spec. in a few cases where the record of the number(s) of specimens is incomplete.
