Deep time and the story of life, sentence 7

Plants reached land, four-legged animals crawled out, and great disasters struck: about 252 million years ago about 90% of sea species died out, and about 66 million years ago an asteroid about 10 km wide hit Mexico and ended the non-bird dinosaurs, leaving room for mammals.

Who acts: Plants, legged animals, great disasters, asteroid · What happens: reach, crawl out, strike, die out, hit, end · To what, where: land, Mexico, non-bird dinosaurs, room
