It is more likely that the Deccan’s influence after the event might have been of greater importance in determining ecological recovery rates after the asteroid …Most verified massive impacts are not associated with a mass extinction event, or even a minor extinction. However, the largest crater less than a billion years old dates from the end of the Cretaceous (near Chicxulub, Mexico). Smaller impacts may not add enough debris to the atmosphere to cause a really devastating impact winter.The Siberian Traps volcanism is widely considered the main cause of the end-Permian mass extinction, the greatest biological crisis in the Earth history.
