An Asteroid And Volcanic Activity: 1-2 Extinction Punch
New evidence supports the theory that both an asteroid impact and volcanic activity triggered widespread extinctions in the Cretaceous period.By Evan Thomas | October 2, 2015
It wasn't just a space rock: More evidence now supports the theory that Earth suffered not one but two simultaneous extinction events at the end of the Cretaceous period.
The asteroid impact linked to the Cretaceous extinction also accelerated volcanic activity in a region of India known as the Deccan Traps.
New research from a team at UC Berkeley shows these two events took place one after the other, at least on a geological timescale.
