Asteroids vs. Volcanos!

A team of Berkeley paleo-everything-ists i.e. botanists, tologists, geologists, etc. have determined that it is a proven fact that a 10 mile wide meteor slammed into the Yucatan peninsula some ten-thousand years ago resulting in an ash, soot and sulphur explosion.  The explosion also triggered world-wide earthquakes reaching "Spinal Tap" scales of 11!  The ash, soot, sulphur and other crap coated the earth's atmosphere which resulted in a cooling period for the earth which killed the dinosaurs.

There is another school of thought who believe it was a chain of giant lava spewing volcanos some 700,000 years prior to the asteroid slam which began killing the dinosaurs because the amount of sulphur emitted from the erupting volcanos is much greater than the impact of a meteor.   Plus the mass extinction was well under way 300,000 years prior to the Yucatan incident.

It is difficult enough for me to plan anything a week in advance let alone trying to wrap my mind around a time-line of hundreds of thousands of years yet the light reflected from the planet at the time of the dinosaurs extinction has not even reached the edge of our own solar system.  So there it is, an argument which spans an unfathomable amount of time possibly concerning what started offing the life on this planet and what finished the job.  Regardless of which side of the argument you may or may not agree upon; contrary to popular opinion, if dinosaurs were still alive today some of them would be movie stars.
