Second thoughts on a rock-art date

Abstract

D.E. Nelson, radiocarbon scientist in the group which reported early dates for rock-art at two Australian sites in ANTIQUITY 64 (1990), reports a further study which leads him to withdraw the published date for one, at Laurie Creek (Northern Territory). As he notes, is co-authors in the 1990 paper are not all in agreement with his present view. The other site dated in 1990, Judds Cavern (Tasmania), is not addressed in this further report.
