# Nanodiamonds in the Younger Dryas boundary sediment layer

D. J. Kennett, J. P. Kennett, A. West et al., 2009. _Science 323(5910), 94_.

Reports cubic diamonds and n-diamonds at about 10 to 3700 ppb in sediments dated 12.9 ± 0.1 ka at multiple North American sites, absent above and below, and interprets them as evidence of a swarm of carbonaceous chondrites or comets.
