Actually this was on TV and I had proposed the many years ago. I thought the 65 million impact in Mexico had caused the massive output of Volcanism in the Caucasus plains near the Black Sea. But according to the TV presentation the Volcanism occurred in India. There may also be a link with the extinction 225 million ago but the impact sight has not been found.

THE BULLET THEORY: A NEW LINK BETWEEN MASS EXTINCTION EVENTS AND ITS IMPLICATIONS FOR HUMANKIND
Benny,
About 2 years ago, I wondered, in my rather amateurish way, whether Impacts and Volcanism could be tied together as causes of mass extinctions, and, inspired by "The Day of the Jackal", proposed a linking theory, which I dubbed the "Bullet Theory". I had a letter published in the UK Journal "Geology Today" in the summer of that year, and emboldened by this, submitted an article - see below - to Scientific American, both its US and Chinese (Ke Xue) versions. The concept was perhaps rightly considered too speculative at the time - but maybe the time has now come for it to be put before a learned if eclectic audience? Perhaps it would now interest members of our Network?
The Bullet Theory proposes a link between two widely held explanations for the demise of the dinosaurs, and, possibly, other Mass Extinction Events. Briefly, these are the Asteroid Impact theory, and the Volcanism theory.
