That news release posted by Mark Minton about dating pictographs is
misleading. The technique it brags about, accelerator mass
spectrometry, is not new. This sort of nonsense is, unfortunately,
typical of the stuff put out by universities' publicity hacks. What
may be new is the sample-preparation technique that the author of the
article uses to get the carbon for AMS without including any old
carbon from the limestone on which the pictographs were drawn. The
article is interesting, and the author is from Texas A&M. Many of his
examples are from Texas. -- Mixon
