Right. In comparing the most logical of the ideas for the demise of the
dinosaur, I suspect that the answer is: E) All or most of the above. When
it comes down to it, there were a heck of a lot of changes happening. I
suspect that the combined effects of all of them was what destroyed the
dominant life forms at the end of the Cretaceous (both aquatic and
terrestrial). Ultimately, I see any bolide impact simply being the coup de
grace of the already stressed ecosystems.
