the C14 dating in the chart in the OP shows every bone they tested to be under 39,000 years old - I am confused as to why you think a 60,000 year dating limit would be an issue in this case?

if the bones were much older wouldnt the C14 be virtually immeasurable? I dont understand why you think it would measure at a higher level and indicate the bones were younger?

it also says here link that C14 dating can be extended to 100,000 years using accelerator techniques which I believe were used in some of the tests listed in the OP

C14 has a half life of only 5730 years. Hence the fraction remaining after 57,300 years is 1/(2^10) = .001 or 0.1%. At that level there is too much random variation for dating to be useful. From high school physics I recall that carbon dating is limited to 60,000 years.

Geological dating, i.e. using the age of rocks and earth layers in which fossils are entombed, is a far more accurate method. Dinosaur bones have been consistently measured at ~65 million or more years.

I have a feeling that this paper was written by folks with an agenda.
