So I've read both of those articles, and I doubt I'm saying anything new here. Steen-Macintyre was not in charge of that archaeological expedition, she was simply a grad student at the time. Grad students are, much to my own dismay, pretty much glorified assistants. Saying that she was a well respected archaeologist at 1966 and that it was 'her' team is incorrect. Also, her career was not ruined in the field, as she went on to publish several more articles, though she did not enjoy a tremendous amount of success. The analyses at that site are still being studied today, and, from what I can tell (although I am not an archaeologist, anthropologist, geologist, etc.) it seems as if the site is complex and has many confounding factors that have influenced the testing. Here is a good essay on the whole thing:
