To be honest, I have never heard the RQ Hypothesis applied to mass
extinctions.  It is usually used to explain the evolution of armor
and teeth and toxic chemicals and the like - and then the evolution
of predators that can handle the defenses.

For instance, the otherwise extremely toxic milkweed has three species
of insect that eat it - all of them co-opting the toxins to protect
themselves, and all of them bright orange and black (the monarch, the
milkweed beetle, and the milkweed bug).
