I'll reply to myself again, sorry. However nice series of maps of continental movement. The site is actually about evolution of ratites (large flightless birds) but does have a picture of continents at various stages. Map of what they call Late Cretaceous about halfway down the page, although at 90 million years I'd tend to call it Mid Cretaceous. As a memory aid you could say the Cretaceous lasted half the time between 130,000,000 years ago and today, ie began then and lasted until 65,000,000 years ago.

And many of you may find this interesting although rather long. Deals with the KT extinction but almost belongs in the climate change thread. Suggests change in CO2, especially from the Deccan eruption, was the cause of extinctions.

And another interesting, but long, one dealing with the problems in the catastrophe theory. Incidently says the eruption started before the asteroid hit.

A comment from this last that I feel is very relevant:

"There are nagging fears that we are overstating the effects of the impact because the results are so clear in North America, close to the impact site."
