Fig. 5. Diagram showing the temporal change of the proportion of "sphaerocones'V'coronates" in the pelagic plateau and basin environments, respectively to 100 m water depth. As for the relation between the percentages and the greater depths, a non-linear relationship is presumed, because the theoretical zero (0%) proportion of the "coronates" could evidently never be reached even in the deepest basins.
