A meteorite impacted Earth. The incoming friction of the meteorite caused widespread wildfires and the burning of Nitrogen in the atmosphere to cause acid rain. dust would have been ejected into the atmosphere, blocking out the Sun, and preventing photosynthesis. Earthquakes and tsunamis would also have resulted from the impact. Because photosynthesis was curtailed, many organisms that could not go without resources for extended periods of time went extinct.
