How did Chicxulub kill all the dinosaurs, yet leave behind other species?
In: Planetary Science
It only killed the big dinosaurs
Big animals need more food. The meteorite (and possibly volcanic activity) means clouds of dust in the air. Clouds of dust in the air means less sunlight. Less sunlight means fewer plants. Fewer plants means less food. Less food mean big animals can eat as much. Not eating enough means you die.
Smaller dinosaurs evolved into modern birds
Small mammals and reptiles survived and became many other species.
