How have scientist been able to determine that such a high % are now gone? I don't think there are enough fossils to make this determination, so how did they get to that number? Do they make extrapolations based on the number of exstinctions that have been recorded in our time and used it to determine how it was back then, or are there other methods?

Crownboy, I'm moving this thread to Evolution/Creation, as I think you'll get livelier response there.
