I just read the Feb. 8 Science paper, literally poured over it and I didn't find any mention of dating pieces of the CAIs. It dealt mostly with oxygen isotopes and some important stuff came out, but no date information. What chronometer did they use? U-Pb? If so, did they do the perovskites? Is it possible the article reference was in error?
