Disruptive selection, like directional selection, favors the extremes traits in a population. Disruptive selection differs in that sudden changes in the environment creates a sudden forces favoring that extreme. Think about the changes in the environment when that meteor crashed into Earth 65mya.

Disruptive selection occurs when extreme phenotypes have a fitness advantage over more intermediate phenotypes. ... Disruptive selection occurs when extreme phenotypes have a fitness advantage over more intermediate phenotypes. The phenomenon is particularly interesting when selection keeps a population in a disruptive regime.

a. Intense natural selection or a disaster can cause a population bottleneck, a severe reduction in population size which reduces the diversity of a population. The survivors have very little genetic variability and little chance to adapt ... C. Disruptive Selection - occurs when two or more character states are favored.
