Radiocarbon dating 101
Since tree rings provide an annual calendar, and some trees live for thousands of years, by C-14 dating the rings themselves one could correct the radiocarbon dates and calibrate the differences. should refer to the year the method was recognized, 1950.
The Bristlecone pine trees in the Sierra Nevada mountains made this possible and today there are international tree ring databases and agreed-upon calibration curves.

Guillermo Gonzalez for sending me the issue of BAR with the Shroud article last November and encouraging me to act on it.
Each radiocarbon date has a statistical probability shown by the ± number.
Upon death, the isotope begins to decay and after 5730±40 years half of it is gone.
The details - the direction of the flow of blood from the wounds, the placement of the nails through the wrists rather than the palms - displays a knowledge of crucifixion that seems too accurate to have been that of a medieval artist.
But two of BAR's savvy readers have objected to our assessment.
But as more dates became available, Egyptologists, who had hieroglyphic records back thousands of years, began to recognize that C-14 dates were generally too young.
They proved this by showing that C-14 dates of wooden artifacts with cartouches (dated royal names) did not agree.
The Shroud of Turin is not, by definition, a work of art but instead belongs to the long and revered tradition of sacred objects that are at once relics and icons.
