No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.

What effects have mass extinctions had on history life?
Mass extinctions have the effect of eliminating a large number of species, which leaves a wide variety of niches open to new species. Whichever species survive the mass extinction quickly evolve into many new forms to fill the empty niches. The Permian-Triassic Extinction Event left niches open to the dinosaurs, and the Cretaceous-Tertiary Extinction eliminated dinosaurs, leaving niches open to mammals.

How many extinctions has earth experienced in its history?
Mass extinctions--at least two--one at the end of the Permian, and one at the end of the Cretaceous, with numerous other less severe events. As far as the extinction of individual species, that list would cover millions of extinct organisms.
