The six largest extinctions were the terminal Cambrian, terminal Ordovician, Late Devonian, terminal Permian, terminal Triassic, and terminal Cretaceous. Since a greater number of genera went extinct in any one of these events that have during the entire Holocene. Palmer, A.R. (1965), Biomere: A New Kind of Biostratigraphic Unit , Journal of Paleontology, vol. 39, pp. 149.
Raup, D. & Sepkoski, J. (1982). "Mass extinctions in the marine fossil record". Science 215: 1501–1503.
Calling the Holocene exitinct event the "Sixth Extinction" is utter crap. The twenty extinction events in the Ordovician to Devonian, the four trilobite biomere extinctions in the Cambrian, terminal Miocene, Ecocene, and Pleistocence extinctions were all of greater magnitude than our current extinction, both in the total number of genera that went extinct and the percentage of know genera that went extinct.
@omegazewargod Just don't take a swim in the Gulf of Mexico right now. My main problem is that it seems oil companies can get the stuff out of the earth easily, but they don't have quick ways to contain it. You would think since they have been doing this stuff for so long, that they would be able to contain it.
