Thanks Utilizer. Since this is coming out of the UK, without yet looking at it closely I'll jump to the conclusion that this is some kind of global warming / no sudden extinctions nonsense from the Church of Darwin.

Finally got my Google back and found this very nice time line article for all Earth’s history.
http://en.wikipedia.org/wiki/Detailed_logarithmic_timeline
Here are a great many interesting charts regarding extinction events and related. If you look at the first chart, first row, you can see a charted labeled Marine Extinctions in blue. It clearly shows a two phase, or ongoing series of extinctions toward the end of the Permian. The second chart in the second line, in orange allows shows a similar wide time period of extinctions for the late Permian. So it appears that the Capitanian falls in this period but the biggest extinction was at the 250 mya time line. I don’t know how to transfer these images. Perhaps someone else could do it?
