# No evidence of nanodiamonds in Younger–Dryas sediments to support an impact event

Tyrone L. Daulton, Nicholas Pinter, Andrew C. Scott, 2010. _Proceedings of the National Academy of Sciences 107(37), 16043–16047_.

Electron-microscopy re-examination of carbon spherules and nanodiamond claims from Younger Dryas boundary sediments; the authors report misidentified graphene and graphene-oxide aggregates and no nanodiamonds.
