Radiocarbon Calibration+<br />

Radiocarbon Years need to be CALIBRATED to Calendric Age<br />

Nanodiamond= Generally microscopic diamond that results from a DETONATION


“The nanodiamonds that we found at all six locations exist<br />

only in sediments associated with the Younger Dryas<br />

Boundary layers, not above it or below it. These discoveries<br />

provide strong evidence for a cosmic impact<br />

event at approximately 12,900 years ago that would<br />

have had enormous environmental consequences for plants,<br />

animals and humans across North America.”<br />
