Was it long-term climate change, rather than a rogue asteroid, that killed off the dinosaurs?
That's the conclusion of German paleontologist Michael Prauss, who studied 65-million-year-old fossils drilled out of the earth in the Brazos River area of Texas and argues that radical changes to the flora and fauna of the era began long before arrival of the massive space rock widely associated with one of the largest mass extinctions in the history of the planet.
That impact, at what is now Chicxulub, Mexico, in the past 30 years has become the primary suspect in the death of the dinosaurs. And it was the subject of an article in the journal Science earlier this month in which 41 scientists from around the world argued that a wealth of global data show the extinctions began at the same time that the asteroid's crash sent debris across the atmosphere and blocked out the sun for years.

comet/meteor impact = climate change
So, the theories would fit each other?
