Carbon dating of the newly unearthed moss suggests that the landslide occurred about 8,100 years ago.

To be fair, most of these discoveries have resulted from intensive archaeological work, from DNA and carbon dating techniques, and from new technologies like satellite imagery.

This sample tested by carbon dating came from a single sample cut from the edge of the Shroud in a section where the cloth was dyed, evidently as part of some medieval repair to match the colour of the original cloth: "The combined evidence from chemical kinetics, analytical chemistry, cotton content, and pyrolysisms proves that the material from the radiocarbon area of the Shroud is significantly different from that of the main cloth.
