Mass extinction is characterized by the loss of 50 - 90 + percent genetically and ecologically diverse species within 1 3.5 Myr intervals. Three conflicting theories exist: (1) Graded Extinction; (2) Stepwise (3) Catastrophic Extinction. These can only be adequately tested with high resolution (cm-scale) stratigraphic data spanning entire mass interval adjacent strata. Such are presently availa...
