Answer:
Dinosaurs, flowers, animals with fur and flowering plants
Explanation:
Mass extinction occurs when more than half of the world’s species die in a geologically short period. A species is a group of organisms similar in appearance, anatomy, physiology, and genetics.
The environment changes so fast that most species can’t adapt or evolve, so they go extinct.
