I'm pretty sure that if you graphed, say, the body masses of a few thousand critters chosen at random you'd get a bell curve, too. Not too good an argument for their all being the same species.
Plotted out as a graph, [fossil dimensions] form the classic bell-shaped curve found using data from modern humans.

It's more likely that you'd get a superposition of bell curves. This would be either multi-modal or maybe just hyperkurtotic.
