Scientists beleive that a large meteorite impacted the Earth, wiping out the dinos.
During this time was a "great extinction", where like 95% of all life simply... died.
That 5% includes bacteria, and bacteria have such small biomass that they would not be affected by the rings.
So what im saying is that Dinosaurs were wiped out by the halos. A silly meteorite couldnt wipe out that much life.
