A vanishingly small percentage.

I once estimated (conservatively) that at least a *trillion* individuals
of Triceratops existed over the span of the genus.  We have remains
of some hundred or so individuals, if you include isolated leg bones
and the like.

Almost certainly less than half, probably less than a quarter.
