Recent comments made to this post by Alan Day refer to this information from the Beta Analytic Lab web site which have become part of this post as of 9/9/2014: "Beta Analytic has set a real and conservative limit of greater than 43500 BP when the activity of the material is statistically the same as the background. This is a credible number based on the lab's own internal AMS limits. As such, Beta Analytic does not quote finite ages in excess of 43500 BP. Samples that yield an activity at or below this are reported as "greater than" 43500 BP."
"- Range: From Present Day back to 47,000 years BP
- Detection Limits: 47,000 BP"
Update 10/08/2014: personal communication from Adam Arkfeld "Jack (the archaeologist willing to help Mr. Arkfeld) had a conversation with one of the techs at Beta and was told that the date provided on the last sample is a reliable minimum age. He ensured Jack that the date is conclusive in that it is at least 43,500. The guy is confident that the sample is ancient. Jack is announcing the date at his upcoming presentation in Richmond this weekend." The tech is essentially saying it is not just "background noise" from the infinite past.

It is indeed smiling.
