Some Info on the Deccans

It is unclear from my preliminary research reading whether the Deccan Traps were erupting in this extreme way prior to the collision. It seems that the massive eruption may have already been going on for some time starting a slow die off of Late Cretaceous fauna caused by global warming as an after effect of the eruption.

One interesting piece of evidence is the Shiva crater - apparently another impact crater of the west coast of India and at the KT Boundary. That's two craters in the same time frame - relatively speaking. Could the collision have been a multi-impact event like the one that hit Jupiter a few years ago? Other than it being described as large, the Shiva crater's dimensions are not mentioned in detail. Is it larger than Chicxulub or smaller? Did both impacts occur together or with a long time period between?

Even with the Deccans erupting prior to impact, the global warming effect would take place over an extended period of time. Most animals and other organisms would surely have had time to adapt or move to better territories. Those most directly and immediately affected would be those living in the region of the Deccan Traps.

Much to think about and more to learn...
