Guaciara M. Santos, Armand Masion, Anne Alexandre, 2018. When the carbon being dated is not what you think it is: Insights from phytolith carbon research. Quaternary Science Reviews 197 (2018) 162-174. https://doi.org/10.1016/j.quascirev.2018.08.007 During phytolith formation, a small amount of carbon (C) can become occluded in the siliceous structure (<1% of the phytolith dry weight). Since […]

Subdecadal phytolith and charcoal records from Lake Malawi, East Africa imply minimal effects on human evolution from the ~74 ka Toba supereruption

Chad L. Yost, Lily J. Jackson, Jeffery R. Stone, Andrew S. Cohen, 2018. Journal of Human Evolution, v. 116, p. 75-94. Our study uses phytoliths and microcharcoal from lake sediments to determine the effects of the Indonesian Mount Toba supereruption at ~75 ka on the climate and vegetation of East Africa. We worked with sediment […]
