The event that is responsible for wiping out of non-avian dinosaurs is is the event of the Cretaceous-Paleogene extinction.

Explanation:

Around '66' million years ago, almost all the tetrapod species, except for a few, suffered mass extinction in an event called "Cretaceous-Paleogene or the Cretaceous-Tertiary extinction". This event is said to have occurred due to the "collision of a huge asteroid" with the Earth which resulted in a tremendous environmental change that drastically lowered the average temperature of the planet and faltered the photosynthesis in plants.
