They, according to some scientists, *may* have been triggered by the K/T, 'dinosaur killer', asteroid impact on the opposite side of the world (Yucatan Peninsula).

Did volcanic eruptions kill the dinosaurs?

Note in particular the last paragraph. It's unlikely that the Deccan Traps were triggered by the Chicxulub impact; this is the first I've heard of a second impact hypothesis.

Thanks, good article.

Here are some interesting links about the K/T events. The first link refers to work by Sankar Chatterjee at item #10. This link also lists at least 5 potential impactors at the time of the dinosaur extinction:

Here is another good one from Texas Tech U.

This site discusses various theories of the Deccan Trapps, including the Shiva Crater aspect:

By all means Google Shiva Crater, Sankar Chatterjee, and Decan Trapps for more details.
