Abstract

Isoleucine epimerization was used to date tooth enamel samples collected from the fossiliferous layers of several Pleistocene formations in the Rome area. To calibrate the isoleucine epimerization rate, we used teeth from the Isernia-La Pineta deposit, dated at approximately 0.70 m.a by K/Ar and Paleomagnetics. The chronological sequence obtained for the deposits is in close agreement with that indicated by biostratigraphic and geologic evidence. The isoleucine epimerization dates represent the first age determinations made directly on the fossil material from the Rome deposits.
