the new theory is that whilst catastrophic environmental occurences will have had an effect, the true cause will have been from insects carrying parasites and evolving diseases that eventually wiped out the dinosaur over a period of a few hundred thousand or million years.
According to George Poinar Jr. a courtesy professor of zoology at Oregon State University:
“There are serious problems with the sudden impact theories of dinosaur extinction, not the least of which is that dinosaurs declined and disappeared over a period of hundreds of thousands, or even millions of years,The full press release is here
That time frame is just not consistent with the effects of an asteroid impact. But competition with insects, emerging new diseases and the spread of flowering plants over very long periods of time is perfectly compatible with everything we know about dinosaur extinction.”
Either way its thought provoking stuff, although, I already didn't like creepy crawlies all that much, and this does them no favours in my book. :s
