How's this for a wild theory.
The end of the dinosaur reign after a major meteorite strike could have been achieved by greatly reducing the world's atmospheric oxygen levels at that time. Is there any evidence of this? It could explain why many of the larger species died out.
Also, would such a meteor strike alter the earth's rotation enough to change climate?
Lots of questions. Does anyone know the answer?
I always thought the Earth's climate changed due to the cloud of particles that blocked the sun and prevented photosynthesis which in turn killed off herbivores then in turn carnivores. That might explain why many sea creatures continued to survive and evolve, as their ocean homes may not have been as affected by the dust clouds??? Does the level of oxygen in the ocean change at the same rate as that of the atmosphere? did the vegetation in the sea die out at the same rate as the terrestrial vegetation?
